GMT Time Display Script?

[blueberry]

GMT Time Script:
http://www.crays.com/jsc/jsC4Udate.htm

Shown below is a script that displays GMT 24-hour time, which should switch from 23:59 to 00:00 at 12 midnight.

However, instead of changing to 00:00, it goes on to show 24:00 - not a big deal, but we know it’s a little funky-looking for some visitors.

At 1am, it finally changes to 01:00…

We would really appreciate it if you could fix this? (Or you might know a better one?)

Thanks so much!!!

Should work, didn't want to reset my clock to test it.

<script type="text/javascript">
  var curDateTime = new Date()
  var curHour = curDateTime.getHours() 
     + curDateTime.getTimezoneOffset()/60
  if (curHour > 24)  curHour -= 24
  if (curHour < 0) curHour += 24
  if (curHour = 24)  curHour = 0
  var curMin = curDateTime.getMinutes()
  var curSec = curDateTime.getSeconds()
  var curTime = 
    ((curHour < 10) ? "0" : "") + curHour + ":" 
    + ((curMin < 10) ? "0" : "") + curMin + ":" 
    + ((curSec < 10) ? "0" : "") + curSec 
  document.write(curTime + " GMT") 
</script>

if (curHour = 24) curHour = 0

That would always set curHour to zero as assignment of 'true' values (those other than an empty string, boolean false, zero [0], null, and undefined) will always evaluate to true.

I know; it was a typo.

The original code could have also been changed so that

if (curHour > 24) curHour -= 24

became:

if (curHour >= 24) curHour -= 24;

Anyway, the simpler approach is:

var now = new Date(),
    h   = now.getUTCHours(),
    m   = now.getUTCMinutes(),
    s   = now.getUTCSeconds();

document.write((h < 10 ? '0' : '') + h + ':'
  + (m < 10 ? '0' : '') + m + ':'
  + (s < 10 ? '0' : '') + s + ' GMT');

The UTC methods return the time without timezone/DST compensation so no adjustments are necessary at all.
