Durations: Convert HH:MM:SS string to seconds

Describe the bug A clear and concise description of what the bug is. I just wanted to know if it’s possible with Dayjs to Convert HH:MM:SS string to seconds. and if it’s not possible would you consider implementing this feature? (I’m available for this feature)

The feature can be used like this:

  const duration = dayjs.duration( '02:04:33', 'HH:mm:ss');

and the function would return something like the following:

const d = '02:04:33';   // your input string
const a = hms.split(':'); // split it at the colons

const result = (+a[0]) * 60 * 60 + (+a[1]) * 60 + (+a[2]); 
console.log(result);

I’ve done the following

const time = '05:22:39'
const [hour, minute, second] = time.split(':').map((t) => parseInt(t))
const duration = dayjs.duration({ hour, minute, second })

The .map() is used to convert each split token to an integer.

I would use a feature, like this. I develop for a video and audio production environment. Taking human formatted duration inputs and changing them to seconds, for calculation, is a very common task. I find durations most useful when summing (i.e. getting total duration of video clips to see if they will fit on a DVD). Using @hamzahamidi example, it would be helpful to have flexibility in the input format (“HH:mm” or “mm:ss”).

    <input class="duration" type="text" value="00:00:05" />
    <input class="duration" type="text" value="00:00:01" />
    <script>
      const total = [...document.querySelectorAll(".duration")]
        .map((time) => time.value)
        .reduce((acc, dur) => acc + dayjs().duration(dur, "HH:mm:ss"), 0);
      console.log(total); // 6
    </script>

Additional duration methods like average, max value, min value, etc, might also be useful.
