Bug description: PHP 5.2 DST logic is bogus
Description:
------------
We do not need PHP to "force" us into accepting its Daylight Savings Time
calculations. Both our database and web boxes are set to Standard time and
we never switch them to DST. We don't WANT PHP's DST logic screwing with
our dates because we don't care about DST when we're posting, reading,
echoing, or even doing date diffs. But I don't see any way in 5.2.9 to tell
it to ignore DST -- you're even deprecating the one switch that seemed to
work in PHP 4.3. So if you're going to do that, we need a switch or an ini
file parameter to tell PHP to ignore DST.
Reproduce code:
---------------
date("M j, Y H:i", (1237787999 - 86400). Exact code is << echo ">Week
#{$row->periodid} WE " . date("M j, Y H:i", ($row->enddate - 86400)) >>. I
gave you the 1237787999 as an example of a date we're retrieving from
mysql.
Expected result:
----------------
I expect to see March 21, 2009 23:59:59, unless you've redefined the
mathematical result of 24 * 60 * 60.
Actual result:
--------------
The actual, "echoed-to-the-screeen" result of this is March 22, 2009
00:59:59. In what universe is this correct? The "1237787999" is an example
of a correct date on our mysql database (returned in a variable and echoed)
and it is the unix timestamp representation of March 22, 2009 23:59:59. If
I subtract 86400 (which USED to be 24 hours) from that, I should get March
21, 2009 23:59:59. This should be simple arithmetic; I should not have to
put up with PHP's DST stuff in doing this.
