ID: 20382 Updated by: [EMAIL PROTECTED] Reported By: nickj-phpbugs at nickj dot org -Status: Assigned +Status: Open Bug Type: Date/time related Operating System: * PHP Version: 5CVS, 4CVS (2004-04-13) Assigned To: derick New Comment:
This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. The Vienna testcase works just fine here, and the Lord Howe testcase shows a bug in the date() function. Compare the PHP script: <?php putenv("TZ=Australia/Lord_Howe"); $tStamp = mktime (17, 17, 17, 1, 1, 1970); echo $tStamp, "\n"; print "tStamp=". date("l Y-m-d H:i:s T", $tStamp). "\n"; $strtotime_tstamp = strtotime("Monday", $tStamp); echo $strtotime_tstamp, "\n"; print "result=".date("l Y-m-d H:i:s T", $strtotime_tstamp)."\n"; print "wanted=Monday 00:00:00\n\n"; ?> output: 26237 tStamp=Thursday 1970-01-01 17:17:17 EST 306000 result=Sunday 1970-01-04 23:00:00 EST wanted=Monday 00:00:00 with the code that the timelib does: [EMAIL PROTECTED]:/dat/dev/timelib$ ./tester-create-ts "1970-01-01 17:17:17 Monday" "" "Australia/Lord_Howe" TS: 306000 | 1970-01-05 00:00:00 LHST Australia/Lord_Howe 0Y 0M 0D / 0H 0M 0S / 0 [EMAIL PROTECTED]:/dat/dev/timelib$ ./tester-render-ts 306000 Australia/Lord_Howe TYPE: 3 TS: 306000 | 1970-01-05 00:00:00 LHST Australia/Lord_Howe You see that the timestamp is the same, but that the date() function renders it wrongly as 1970-01-04 23:00:00 EST while it should have been 1970-01-05 00:00:00 LHST. The EST is not even part of the timezone information for Lord Howe. Closing bug. (But feel free to report a new one for the date() function). Previous Comments: ------------------------------------------------------------------------ [2005-06-19 14:10:06] [EMAIL PROTECTED] These new tests are all correct, except the one for Vienna and perhaps the one for Lord Howe. They are correct because there is no 00:00 for those specific dates, as the time goes from: 23:59 winter time to 01:00 summer time the clock is set an hour forward there. I'll check out the Vienna and Lord Howe ones now, can you please file a different bug for the rendering problem on Windows? ------------------------------------------------------------------------ [2005-06-19 03:44:18] nickj-phpbugs at nickj dot org That's a lot better, it takes much longer to find problems, but there are still some cases it doesn't seem to work on (using the same Debian GNU/Linux Woody 3.0r6 system), such as: =============================================================== <?php putenv("TZ=Europe/Tirane"); $tStamp = mktime (17, 17, 17, 1, 4849, 1970); print "tStamp=". date("l Y-m-d H:i:s T", $tStamp).

The ones that don't work seem to differ between operating systems.
