So do I:
echo "<br>Mkt: " . mktime(0,0,0,1,1,1970);
echo "<br>GMT: " . gmmktime(0,0,0,1,1,1970);
produces
Mkt: 0
GMT: -3600
BTW I'm running PHP under WinNT4.0
mktime -- Get UNIX timestamp for a date
(http://www.php.net/manual/en/function.mktime.php)
Returns the Unix timestamp corresponding to the arguments given. This timestamp is a
long integer containing the number
of seconds between the Unix Epoch (January 1 1970) and the time specified.
gmmktime -- Get UNIX timestamp for a GMT date
(http://www.php.net/manual/en/function.gmmktime.php)
Identical to mktime() except the passed parameters represents a GMT date.
Given that 1Jan1970 was not in Summer time, I would expect that a localised British
(etc) machine would deliver the same
answer from both functions. So there's some logic here that I don't follow either.
Perhaps someone of greater mind...?
I will send you a sandbox routine I made up when I was playing with times and dates,
and trying to get a handle on
working in GMT to settle (WORLD wide web) relative time-ing issues. It's not flash,
but happily dumps out various
date/time function results and illustrates the various argument/format choices (I'm
not sure of list rules, so I'll send
it privately - if anyone else wants it, please email me directly. HTH). Run it today -
you'll get the "rd" after 23rd,
and this week - to get a GMT/BST difference!
Here's a sample run:
