#22198 [Ana->Csd]: date() returning incorrect date

ID: 22198 Updated by: vrana@php.net Reported By: jm at sindigit dot pt -Status: Analyzed +Status: Closed Bug Type: Documentation problem Operating System: Solaris 8 (sparc) PHP Version: 4.3.0 New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "Some times are invalid if DST is on. If DST is enabled in e.g. 2:00, all times between 2:00 and 3:00 are invalid and mktime returns undefined (usually negative) value. Some systems (e.g. Solaris 8) enable DST in midnight so time 0:30 of the day when DST is enabled is evaluated as 23:30 of the previous day."
