Bug #10694 Updated: mktime leap year bug

ID: 10694 Updated by: derick Reported By: schnitten@gmx.at Old-Status: Open Status: Assigned Bug Type: Date/time related Operating system: PHP Version: 4.0.4 Assigned To: derick Comments: Assigning to myself Previous Comments: --------------------------------------------------------------------------- [2001-05-07 01:50:21] schnitten@gmx.at first of all: I use php 4.0.1pl2 and don't have the possibility to upgrade. Please verify with latest version. I tried to add 12 months to a given timestamp and figured out that mktime() doesn't include a 29th February into its calculations. Effect is, that following code doesn't jump forward 1 year during each loop. Every leap year 1 day gets lost! $a = mktime(0,0,0,1,1,1970); for ($i=0; $i<20; $i++) { $a = mktime(0,0,3600 +$a,1+12,1,1970); $b = date("d-m-Y", $a); print "Date: $b<br>"; } --------------------------------------------------------------------------- ATTENTION!
