Daylight savings time.... use gmdate in this case.

Daylight saving time I guess. I thought it should happen
between 2am and 3am, but that's maybe just where I am.

While trying to get a list of dates between any two given dates by adding 86400 (secs
per day) to each consecutive datetime, I discovered that adding 86400 (secs per day)
to the 3rd Sunday of March (in any year) results in a datetime which is interpreted by
the date() function as 23:00 hrs on the same Sunday - rather then 00:00 hr on the
following day, as it should be.
There also seems to be a similar effect in reverse some time in October.
Have a look at the result of the following script, using any range of dates in
$datetime_temp and $datetime_end.
<?php
$datetime_temp = strtotime("2002-1-1");
$datetime_end = strtotime("2002-12-31");
echo "start: ".date("Y-n-j H:i:s", $datetime_temp);
echo " end: ".date("Y-n-j H:i:s", $datetime_end)."<br/>\n";
$datetimes = array();
while($datetime_temp <= $datetime_end) {
$datetimes[] = $datetime_temp;
echo date("Y-n-j H:i:s", $datetime_temp)."<br/>\n";
$datetime_temp += 86400;
}
?>
Partial output:

What's happening?
Is there another/better way for me to get my list of dates?
