#28599 [NEW]: strtotime fails with certain intervals

From: fr33k at techie dot com Operating system: Debian PHP version: 4.3.5 PHP Bug Type: Date/time related Bug description: strtotime fails with certain intervals Description: ------------ When strtotime encounters certain intervals while using a zero "now" time as the second argument, it fails. Some intervals fail, others work fine. All worked fine with a non-zero "now" date. I was using this as a convenient way to translate intervals like "+1 Week" into seconds. 0+1 Day: 86400 0+2 Days: 172800 +3 Days: 1086327304 104022382+3 Days: 104281582 0+3 Days: -1 +332 Days: 1114752904 0+332 Days: -1 0+1 Week: -1 0+4 Weeks: -1 0+1 Month: 2678400 0+3 Months: 7776000 0+1 Year: 31536000 0+4 Years: 126230400 Reproduce code: --------------- print "0+2 Days: ".strtotime('+2 Days',0)."\n"; print "+3 Days: ".strtotime('+3 Days')."\n"; print "104022382+3 Days: ".strtotime('+3 Days',104022382)."\n"; print "0+3 Days: ".strtotime('+3 Days',0)."\n"; print "+332 Days: ".strtotime('+332 Days')."\n"; print "0+332 Days: ".strtotime('+332 Days',0)."\n"; print "0+1 Week: ".strtotime('+1 Week',0)."\n"; print "0+4 Weeks: ".strtotime('+4 Weeks',0)."\n"; print "0+3 Months: ".strtotime('+3 Months',0)."\n"; print "0+1 Year: ".strtotime('+1 Year',0)."\n"; Expected result: ---------------- 0+2 Days: 172800 +3 Days: 1086327494 104022382+3 Days: 104281582 0+3 Days: 259200 +332 Days: 1114753094 0+332 Days: 28684800 0+1 Week: 604800 0+4 Weeks: 2419200 0+3 Months: 7776000 0+1 Year: 31536000 Actual result: -------------- 0+2 Days: 172800 +3 Days: 1086327494 104022382+3 Days: 104281582 0+3 Days: -1 +332 Days: 1114753094 0+332 Days: -1 0+1 Week: -1 0+4 Weeks: -1 0+3 Months: 7776000 0+1 Year: 31536000 -- Edit bug report at http://bugs.php.net/?id=28599&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28599&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28599&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28599&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28599&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28599&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28599&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28599&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28599&r=support Expected behavior: http://bugs.php.net/fix.php?id=28599&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28599&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28599&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28599&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28599&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28599&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28599&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28599&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28599&r=float
