From: [EMAIL PROTECTED] Operating system: Linux PHP version: 4.2.3 PHP Bug Type: Date/time related Bug description: Remove is_dst parameter from gmmktime?
Passing anything but -1 for the is_dst argument of gmmktime can result in times that are off by an hour, if the system's local time zone uses DST. For example, I assumed that passing 0 would the right thing to do (not in DST), but if the date falls within my local DST range, the time I get back is an hour ahead. This is because, internally, PHP calls mktime and then tries to adjust the local time to GMT. Of course, this is easy enough to work around, and I will put a note on the manual page, but I still think the parameter is irrelevant for gmmktime, and since its use can cause errors, it would be nice if it were removed, or at least ignored (if one wants to avoid breaking existing code; although a warning would probably be good). /* Demostrate problem with gmmktime() */ // These should produce the same value, as GMT has no DST. echo gmmktime(0, 0, 0, 7, 23, 2002, 0) ."\n"; echo gmmktime(0, 0, 0, 7, 23, 2002) .
