#33532 [Asn]: Different output for strftime() and date()

ID: 33532 Updated by: derick@php.net Reported By: nickj-phpbugs at nickj dot org Status: Assigned Bug Type: Date/time related Operating System: Debian Woody GNU/Linux 3.0r6 PHP Version: 5CVS-2005-07-01 (dev) Assigned To: derick New Comment: Yeha, but this is a strftime() problem, not a date() problem ;-) Previous Comments: ------------------------------------------------------------------------ [2005-07-01 09:38:52] sniper@php.net Derick was working on a new *date() implementation too.. ------------------------------------------------------------------------ [2005-07-01 06:15:47] nickj-phpbugs at nickj dot org Description: ------------ Getting different output for strftime() and date(), and wondering whether these should be the same. Example code: <?php print "TZ has NOT been set\n"; print "Should strftime==datestr? Strftime seems to assume GMT tStamp.\n"; $input = "10:00:00 AM July 1 2005"; print "input " . $input . "\n"; $tStamp = strtotime($input); print "strftime " . strftime("%r %B%e %Y", $tStamp) . "\n"; print "datestr " . date ("H:i:s A F j Y", $tStamp) . "\n"; print "\nSetting TZ\n"; putenv ("TZ=Australia/Sydney"); $input = "10:00:00 AM July 1 2005"; print "input " . $input . "\n"; $tStamp = strtotime($input); print "strftime " . strftime("%r %B%e %Y", $tStamp) . "\n"; print "datestr " . date ("H:i:s A F j Y", $tStamp) . "\n"; ?> Output: ------------------------------------------------- ludo:~/tmp/php-5.1-dev/strftime-vs-date# ../php5-200507010030/sapi/cli/php ./strftime-vs-date.php TZ has NOT been set Should strftime==datestr? Strftime seems to assume GMT tStamp. input 10:00:00 AM July 1 2005 strftime 08:00:00 PM July 1 2005 datestr 10:00:00 AM July 1 2005 Setting TZ input 10:00:00 AM July 1 2005 strftime 10:00:00 AM July 1 2005 datestr 10:00:00 AM July 1 2005 ludo:~/tmp/php-5.1-dev/strftime-vs-date# ------------------------------------------------- Expected output: ------------------------------------------------- TZ has NOT been set Should strftime==datestr? Strftime seems to assume GMT tStamp. input 10:00:00 AM July 1 2005 strftime 10:00:00 AM July 1 2005 datestr 10:00:00 AM July 1 2005 Setting TZ input 10:00:00 AM July 1 2005 strftime 10:00:00 AM July 1 2005 datestr 10:00:00 AM July 1 2005 ludo:~/tmp/php-5.1-dev/strftime-vs-date# ------------------------------------------------- Note: the "%r" strftime format is described thus: "time in a.m. and p.m. notation". The strftime documentation does not indicate that this is altered by the locale settings (unlike the weekday, month, and so on are). However my locale is English anyway, which is what date() seems to use, and the locale is not adjusted by the above script, so I would anticipate getting the same output between date and strftime. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33532&edit=1
