Please see the code below. The comments are the result of running this
code on my PC, (my GMT Offset = +2 hours = +7200 sec.)
You may see that the mktime() and date() functions work correct, but
gmmktime() returns wrong value in winter time (when it is not a
daylight saving time), and gmdate returns wrong "Z" parameter.
Note: this bug does not appear on UNIX systems.
<?
$df="d.m.Y - H:i:s (Z), I";
$t=mktime(0,0,0,1,2,1970);
echo "<br><b>Make 02.01.1970 - 00:00:00 (Local):</b><br>",
"Timestamp: $t<br>", // 79200
"GMT: ", gmdate($df,$t), "<br>", // 01.01.1970 - 22:00:00 (7200)
"Local: ", date($df,$t), "<br>", // 02.01.1970 - 00:00:00 (7200)
"----------------------------------------<br>";
$t=gmmktime(0,0,0,1,2,1970);
echo "<br><b>Make 02.01.1970 - 00:00:00 (GMT):</b><br>",
"Timestamp: $t<br>", // 82800 (Why !=86400 ?)
"GMT: ", gmdate($df,$t), "<br>", // 01.01.1970 - 23:00:00 (7200)
"Local: ", date($df,$t), "<br>", // 02.01.1970 - 01:00:00 (7200)
"----------------------------------------<br>";
$t=mktime(0,0,0,7,20,1970);
echo "<br><b>Make 20.07.1970 - 00:00:00 (Local):</b><br>",
"Timestamp: $t<br>", // 17269200
"GMT: ", gmdate($df,$t), "<br>", // 01.07.1970 - 21:00:00 (7200)
"Local: ", date($df,$t), "<br>", // 02.07.1970 - 00:00:00 (10800)
"----------------------------------------<br>";
$t=gmmktime(0,0,0,7,20,1970);
echo "<br><b>Make 20.07.1970 - 00:00:00 (GMT):</b><br>",
"Timestamp: $t<br>", // 17280000 (=86400*200)
"GMT: ", gmdate($df,$t), "<br>", // 02.07.1970 - 00:00:00 (7200)
"Local: ", date($df,$t), "<br>", // 02.07.1970 - 03:00:00 (10800)
"----------------------------------------<br>";
