PHP 4.0 Bug #7203 Updated: Lack of calling tzset() in some php internal code

ID: 7203 Updated by: sniper Reported By: christian.robert@polymtl.ca Old-Status: Assigned Status: Closed Bug Type: Date/time related Assigned To: Comments: Fixed in CVS. Thank you for pointing this out. --Jani Previous Comments: --------------------------------------------------------------------------- [2001-01-02 17:58:08] derick@php.net The tzset documentation on Linux says this: The tzset() function initializes the tzname variable from the TZ environment variable. This function is automati­ cally called by the other time conversion functions that depend on the time zone. But strftime is really a libc thingy, and is not emulated in PHP. Please also try php 4.0.4, there where some fixes in it that had to do with date and time stuff. --------------------------------------------------------------------------- [2000-10-14 04:27:04] christian.robert@polymtl.ca I recently found a problem on a php piece of code who looks like: putenv("TZ=$Some_TZ"); // Like "EST5EDT" $val= strftime("%Z"); echo "Timezone = ".$val; It sometimes get the right value, sometimes some "near" garbage values. Not repeateable (at random under apache). it looks like that under standard linux(glibc2), all "time" related function should call "C" function tzset() before first usage. I see in the source that: _php_mktime() is calling tzset() #if HAVE_TZSET the strftime() function need this too (for linux at least) thanks, Xtian. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=7203
