I'm writing a timeclock for work, but have a problem processing 12 hour times:

--Script--
<?php
$T=array('05:00 PM','05:00PM','5:00 PM','5:00PM');
foreach ($T as $TIME)
{
  echo $TIME.'<br>';
  echo strtotime($TIME).'<br>';
  echo date("Y-m-d h:i:s",strtotime($TIME)).'<br><br>';
}
?>

--Output--
05:00 PM
1026432000
2002-07-11 05:00:00

05:00PM
1026432000
2002-07-11 05:00:00

5:00 PM
1026432000
2002-07-11 05:00:00

5:00PM
1026432000
2002-07-11 05:00:00

I've compiled PHP 4.2.1 for Apache 2.0.39 with SSLOpen 0.9.7 beta 2.  PHP is installed as a module.

Is it me or my box?
Thanks in advance,
Mike Wilmes

Your script is buggy. Read this manual page a bit more carefully: http://www.php.net/manual/en/function.date.php

h - hour, 12-hour format; i.e. "01" to "12"                  H - hour, 24-hour format; i.e. "00" to "23"

NOT BOGUS.

sniper@php.net, you missed his point entirely. His code is correct.

strotime() doesn't account for the 12 hour format being passed in, that's the 
issue. The time string returned is passed to date(), which outputs correctly 
strtotime()'s invalid conversion of the text string.

The issue is when a 12 hour format time like 5:00 PM is passed in, it always 
returns with 5:00 AM.

He is obviously using h for the date output, but that's not important what-so-
ever. This should be fixed.

I think you jumped the gun, 05:00:00 is correct but the AM / PM was ommitted from 
the output

Oops, disregard.
