Überprüfen Sie den Zeitunterschied in Javascript

Wie würden Sie den Zeitunterschied zwischen zwei Textfeldern in Javascript überprüfen?

Improvisieren. Subtrahieren Sie JavaScript- DateObjekte, um ihren Unterschied zu ermitteln:

// use a constant date (e.g. 2000-01-01) and the desired time to initialize two dates

var date1 = new Date(2000, 0, 1,  9, 0); // 9:00 AM
var date2 = new Date(2000, 0, 1, 17, 0); // 5:00 PM

// the following is to handle cases where the times are on the opposite side of
// midnight e.g. when you want to get the difference between 9:00 PM and 5:00 AM

if (date2 < date1) {
    date2.setDate(date2.getDate() + 1);
}

var diff = date2 - date1;

// 28800000 milliseconds (8 hours)

Sie können dann Millisekunden wie folgt in Stunden, Minuten und Sekunden konvertieren:

var msec = diff;
var hh = Math.floor(msec / 1000 / 60 / 60);
msec -= hh * 1000 * 60 * 60;
var mm = Math.floor(msec / 1000 / 60);
msec -= mm * 1000 * 60;
var ss = Math.floor(msec / 1000);
msec -= ss * 1000;
// diff = 28800000 => hh = 8, mm = 0, ss = 0, msec = 0

Sie können die Zeit als Zeichenfolge wie folgt in ein 24-Stunden-Format konvertieren:

function parseTime(s) {
    var part = s.match(/(\d+):(\d+)(?: )?(am|pm)?/i);
    var hh = parseInt(part[1], 10);
    var mm = parseInt(part[2], 10);
    var ap = part[3] ? part[3].toUpperCase() : null;
    if (ap === "AM") {
        if (hh == 12) {
            hh = 0;
        }
    }
    if (ap === "PM") {
        if (hh != 12) {
            hh += 12;
        }
    }
    return { hh: hh, mm: mm };
}
parseTime("12:00 AM"); // {hh:  0, mm: 0}
parseTime("12:00 PM"); // {hh: 12, mm: 0}
parseTime("01:00 PM"); // {hh: 13, mm: 0}
parseTime("23:00");    // {hh: 23, mm: 0}

Diese Funktion gibt eine Zeichenfolge zurück, die sich von einer Datums- / Uhrzeitzeichenfolge und der aktuellen Datums- / Uhrzeitzeichenfolge unterscheidet.

function get_time_diff( datetime )
{
    var datetime = typeof datetime !== 'undefined' ? datetime : "2014-01-01 01:02:03.123456";

    var datetime = new Date( datetime ).getTime();
    var now = new Date().getTime();

    if( isNaN(datetime) )
    {
        return "";
    }

    console.log( datetime + " " + now);

    if (datetime < now) {
        var milisec_diff = now - datetime;
    }else{
        var milisec_diff = datetime - now;
    }

    var days = Math.floor(milisec_diff / 1000 / 60 / (60 * 24));

    var date_diff = new Date( milisec_diff );

    return days + " Days "+ date_diff.getHours() + " Hours " + date_diff.getMinutes() + " Minutes " + date_diff.getSeconds() + " Seconds";
}

In Google Chrome getestet console(drücken Sie F12)

get_time_diff()
1388534523123 1375877555722
"146 Days 12 Hours 49 Minutes 27 Seconds"

Hier ist die Lösung, die für mich funktioniert hat:

var date1 = new Date("08/05/2015 23:41:20");
var date2 = new Date("08/06/2015 02:56:32");

var diff = date2.getTime() - date1.getTime();

var msec = diff;
var hh = Math.floor(msec / 1000 / 60 / 60);
msec -= hh * 1000 * 60 * 60;
var mm = Math.floor(msec / 1000 / 60);
msec -= mm * 1000 * 60;
var ss = Math.floor(msec / 1000);
msec -= ss * 1000;

alert(hh + ":" + mm + ":" + ss);

Hier ist meine Wiedergabe ....

function get_time_difference(earlierDate, laterDate) 
{
    var oDiff = new Object();

    //  Calculate Differences
    //  -------------------------------------------------------------------  //
    var nTotalDiff = laterDate.getTime() - earlierDate.getTime();

    oDiff.days = Math.floor(nTotalDiff / 1000 / 60 / 60 / 24);
    nTotalDiff -= oDiff.days * 1000 * 60 * 60 * 24;

    oDiff.hours = Math.floor(nTotalDiff / 1000 / 60 / 60);
    nTotalDiff -= oDiff.hours * 1000 * 60 * 60;

    oDiff.minutes = Math.floor(nTotalDiff / 1000 / 60);
    nTotalDiff -= oDiff.minutes * 1000 * 60;

    oDiff.seconds = Math.floor(nTotalDiff / 1000);
    //  -------------------------------------------------------------------  //

    //  Format Duration
    //  -------------------------------------------------------------------  //
    //  Format Hours
    var hourtext = '00';
    if (oDiff.days > 0){ hourtext = String(oDiff.days);}
    if (hourtext.length == 1){hourtext = '0' + hourtext};

    //  Format Minutes
    var mintext = '00';
    if (oDiff.minutes > 0){ mintext = String(oDiff.minutes);}
    if (mintext.length == 1) { mintext = '0' + mintext };

    //  Format Seconds
    var sectext = '00';
    if (oDiff.seconds > 0) { sectext = String(oDiff.seconds); }
    if (sectext.length == 1) { sectext = '0' + sectext };

    //  Set Duration
    var sDuration = hourtext + ':' + mintext + ':' + sectext;
    oDiff.duration = sDuration;
    //  -------------------------------------------------------------------  //

    return oDiff;
}

Eine gute Lösung ist bei verfügbar

http://blogs.digitss.com/javascript/calculate-datetime-difference-simple-javascript-code-snippet/

gibt die Ausgabe in Ihrem gewünschten Differenzformat von

Tage: Stunden: Minuten: Sekunden.

Eine leicht modifizierte Version dieses Codes ist unten dargestellt

 var vdaysdiff; // difference of the dates
   var vhourDiff;
   var vmindiff;
   var vsecdiff;

   vdaysdiff = Math.floor(diff/1000/60/60/24);  // in days
   diff -= vdaysdiff*1000*60*60*24;

   vhourDiff = Math.floor(diff/1000/60/60);  // in hours
   diff -= vhourDiff*1000*60*60;

   vmindiff = Math.floor(diff/1000/60); // in minutes
   diff -= vmindiff*1000*60;

   vsecdiff= Math.floor(diff/1000);  // in seconds

   //Text formatting
   var hourtext = '00';
   if (hourDiff > 0){ hourtext = String(hourDiff);}
   if (hourtext.length == 1){hourtext = '0' + hourtext};                                                              

   var mintext = '00';                           
   if (mindiff > 0){ mintext = String(mindiff);}
   if (mintext.length == 1){mintext = '0' + mintext};

  //shows output as HH:MM ( i needed shorter duration)
   duration.value= hourtext + ':' + mintext;

Dies ist eine Ergänzung zu dmd733s Antwort. Ich habe den Fehler mit der Tagesdauer behoben (nun, ich hoffe, ich konnte nicht jeden Fall testen).

Ich habe dem Ergebnis auch schnell eine String-Eigenschaft hinzugefügt, die die verstrichene allgemeine Zeit enthält (Entschuldigung für die schlecht verschachtelten ifs !!). Zum Beispiel, wenn es für die Benutzeroberfläche verwendet wird und angibt, wann etwas aktualisiert wurde (wie ein RSS-Feed). Irgendwie fehl am Platz, aber schön zu haben:

function getTimeDiffAndPrettyText(oDatePublished) {

  var oResult = {};

  var oToday = new Date();

  var nDiff = oToday.getTime() - oDatePublished.getTime();

  // Get diff in days
  oResult.days = Math.floor(nDiff / 1000 / 60 / 60 / 24);
  nDiff -= oResult.days * 1000 * 60 * 60 * 24;

  // Get diff in hours
  oResult.hours = Math.floor(nDiff / 1000 / 60 / 60);
  nDiff -= oResult.hours * 1000 * 60 * 60;

  // Get diff in minutes
  oResult.minutes = Math.floor(nDiff / 1000 / 60);
  nDiff -= oResult.minutes * 1000 * 60;

  // Get diff in seconds
  oResult.seconds = Math.floor(nDiff / 1000);

  // Render the diffs into friendly duration string

  // Days
  var sDays = '00';
  if (oResult.days > 0) {
      sDays = String(oResult.days);
  }
  if (sDays.length === 1) {
      sDays = '0' + sDays;
  }

  // Format Hours
  var sHour = '00';
  if (oResult.hours > 0) {
      sHour = String(oResult.hours);
  }
  if (sHour.length === 1) {
      sHour = '0' + sHour;
  }

  //  Format Minutes
  var sMins = '00';
  if (oResult.minutes > 0) {
      sMins = String(oResult.minutes);
  }
  if (sMins.length === 1) {
      sMins = '0' + sMins;
  }

  //  Format Seconds
  var sSecs = '00';
  if (oResult.seconds > 0) {
      sSecs = String(oResult.seconds);
  }
  if (sSecs.length === 1) {
      sSecs = '0' + sSecs;
  }

  //  Set Duration
  var sDuration = sDays + ':' + sHour + ':' + sMins + ':' + sSecs;
  oResult.duration = sDuration;

  // Set friendly text for printing
  if(oResult.days === 0) {

      if(oResult.hours === 0) {

          if(oResult.minutes === 0) {
              var sSecHolder = oResult.seconds > 1 ? 'Seconds' : 'Second';
              oResult.friendlyNiceText = oResult.seconds + ' ' + sSecHolder + ' ago';
          } else { 
              var sMinutesHolder = oResult.minutes > 1 ? 'Minutes' : 'Minute';
              oResult.friendlyNiceText = oResult.minutes + ' ' + sMinutesHolder + ' ago';
          }

      } else {
          var sHourHolder = oResult.hours > 1 ? 'Hours' : 'Hour';
          oResult.friendlyNiceText = oResult.hours + ' ' + sHourHolder + ' ago';
      }
  } else { 
      var sDayHolder = oResult.days > 1 ? 'Days' : 'Day';
      oResult.friendlyNiceText = oResult.days + ' ' + sDayHolder + ' ago';
  }

  return oResult;
}

Als ich den Unterschied zwischen dem gleichen Zeitstempel versuchte, gab es 0 Tage 5 Stunden 30 Minuten

Um es genau zu bekommen, habe ich 5 Stunden und 30 Minuten abgezogen

function get_time_diff( datetime )
{
var datetime = typeof datetime !== 'undefined' ? datetime : "2014-01-01 01:02:03.123456";

var datetime = new Date(datetime).getTime();
var now = new Date().getTime();

if( isNaN(datetime) )
{
    return "";
}

console.log( datetime + " " + now);

if (datetime < now) {
    var milisec_diff = now - datetime;
}else{
    var milisec_diff = datetime - now;
}

var days = Math.floor(milisec_diff / 1000 / 60 / (60 * 24));

var date_diff = new Date( milisec_diff );

return days + "d "+ (date_diff.getHours() - 5) + "h " + (date_diff.getMinutes() - 30) + "m";
}

Die Zeitdifferenz in Millisekunden

firstDate.getTime() - secondDate.getTime() 

Ich habe einige Verbesserungen für den Timer-Zähler vorgenommen

//example return : 01:23:02:02
//               : 1 Day 01:23:02:02
//               : 2 Days 01:23:02:02 


function get_timeDifference(strtdatetime) {
    var datetime = new Date(strtdatetime).getTime();
    var now = new Date().getTime();

    if (isNaN(datetime)) {
        return "";
    }

    //console.log(datetime + " " + now);

    if (datetime < now) {
        var milisec_diff = now - datetime;
    } else {
        var milisec_diff = datetime - now;
    }

    var days = Math.floor(milisec_diff / 1000 / 60 / (60 * 24));

    var date_diff = new Date(milisec_diff);





    var msec = milisec_diff;
    var hh = Math.floor(msec / 1000 / 60 / 60);
    msec -= hh * 1000 * 60 * 60;
    var mm = Math.floor(msec / 1000 / 60);
    msec -= mm * 1000 * 60;
    var ss = Math.floor(msec / 1000);
    msec -= ss * 1000


    var daylabel = "";
    if (days > 0) {
        var grammar = " ";
        if (days > 1) grammar = "s " 
        var hrreset = days * 24;
        hh = hh - hrreset;
        daylabel = days + " Day" + grammar ;
    }


    //  Format Hours
    var hourtext = '00';
    hourtext = String(hh);
    if (hourtext.length == 1) { hourtext = '0' + hourtext };

    //  Format Minutes
    var mintext = '00';
    mintext = String(mm); 
    if (mintext.length == 1) { mintext = '0' + mintext };

    //  Format Seconds
    var sectext = '00';
    sectext = String(ss); 
    if (sectext.length == 1) { sectext = '0' + sectext };

    var msectext = '00';
    msectext = String(msec);
    msectext = msectext.substring(0, 1);
    if (msectext.length == 1) { msectext = '0' + msectext };

    return daylabel + hourtext + ":" + mintext + ":" + sectext + ":" + msectext;
}

Versuche dies :

function SumHours() {
  var smon = document.getElementById('sMon').value ;
  var fmon = document.getElementById('fMon').value ;
  var diff = 0 ;
  if (smon && fmon) {
    smon = ConvertToSeconds(smon);
    fmon = ConvertToSeconds(fmon);
    diff = Math.abs( fmon - smon ) ;
    console.log( 'time difference is : ' + secondsTohhmmss(diff) );
  }

  function ConvertToSeconds(time) {
    var splitTime = time.split(":");
    return splitTime[0] * 3600 + splitTime[1] * 60;
  }

  function secondsTohhmmss(secs) {
    var hours = parseInt(secs / 3600);
    var seconds = parseInt(secs % 3600);
    var minutes = parseInt(seconds / 60) ;
    return hours + "hours : " + minutes + "minutes ";
  }
}

<td>
  <input type="time" class="dataInput" id="sMon" onchange="SumHours();" />
</td>

<td>
  <input type="time" class="dataInputt" id="fMon" onchange="SumHours();"/>
</td>

Ich würde nur getTime();und zum Beispiel verwenden Date.now(), um die Differenz in Millisekunden zurückzugeben:

 //specified date:

var oneDate = new Date("November 02, 2017 06:00:00");

//number of milliseconds since midnight Jan 1 1970 till specified date

var oneDateMiliseconds = oneDate.getTime();

////number of milliseconds since midnight Jan 1 1970 till now

var currentMiliseconds = Date.now(); 

//return time difference in miliseconds

alert(currentMiliseconds-oneDateMiliseconds);

You can Get Two Time Different with this function. 

 /**
     * Get Two Time Different
     * @param join
     * @param lastSeen
     * @param now
     * @returns {string}
     */
    function getTimeDiff( join, lastSeen, now = false)
    {
        let t1 = new Date(join).getTime(), t2 = new Date(lastSeen).getTime(), milliseconds =0, time ='';
        if (now) t2 = Date.now();
        if( isNaN(t1) || isNaN(t2) ) return '';
        if (t1 < t2) milliseconds = t2 - t1; else milliseconds = t1 - t2;
        var days = Math.floor(milliseconds / 1000 / 60 / (60 * 24));
        var date_diff = new Date( milliseconds );
        if (days > 0) time += days + 'd ';
        if (date_diff.getHours() > 0) time += date_diff.getHours() + 'h ';
        if (date_diff.getMinutes() > 0) time += date_diff.getMinutes() + 'm ';
        if (date_diff.getSeconds() > 0) time += date_diff.getSeconds() + 's ';
        return time;
    }
    
    
    console.log(getTimeDiff(1578852606608, 1579530945513));
    

Ich mache es gerne über Epoch.

var now = new Date();
var future = new Date(now.setMinutes(15));

var futureEpoch = moment(future).unix();
var nowEpoch = moment(now).unix();
var differenceInEpoch = nowEpoch - scheduledEpoch ;

console.log("futureEpoch        : " + futureEpoch);
console.log("nowEpoch              : " + nowEpoch);
console.log("differenceInEpoch     : " + differenceInEpoch);

var diffTime = new Date(0); // The 0 there is the key, which sets the date to the epoch
diffTime.setUTCSeconds(differenceInEpoch);
console.log("new diffTime : " + diffTime);

In meinem Fall werde ich die Zeit in Millisekunden im Chromspeicher speichern und versuchen, den Unterschied in Stunden später zu finden.

function timeDiffInHours(milliseconds){
    time_diff = (new Date).getTime() - milliseconds
    return parseInt((time_diff/(1000*60*60)) % 24)
}

// This is again sending current time and diff would be 0.
timeDiffInHours((new Date).getTime());  

Sie können moment js für diesen Zweck verwenden. momentJs 'fromNow ()' gibt Ihnen einen Zeitunterschied zur aktuellen Zeit.

var m1 = any date time on moment format;

console.log(m1.fromNow());

Holen Sie sich die Eingabewerte nach dem Absenden des Formulars in PHP

$start_time = $_POST('start_time');
$end_time =$_POST('end_time');
$start = $start_time;
$end = $end_time;
$datetime1 = new DateTime($end);
$datetime2 = new DateTime($start);
//echo $datetime1->format('H:i:s');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%h:%i');
$time = explode(":",$elapsed);
$hours = $time[0];
$minutes = $time[1];
$tminutes = $minutes + ($hours*60);

Die Variable $ tminutes ist der Gesamtunterschied in Minuten, die Arbeitsstunde ist $ hour. Dieser Code ist für PHP. Verwenden Sie diese Logik und konvertieren Sie diesen Code in js
