#44909 [Opn->WFx]: strtotime doesn't recognize UT timezone

ID: 44909 Updated by: derick@php.net Reported By: selsky at columbia dot edu -Status: Open +Status: Wont fix Bug Type: Date/time related Operating System: Solaris PHP Version: 5.2.6 New Comment: The comments to go with the line 384 you're mentioned are actually incorrect. RFC2822 in section 3.1, paragraph 3 it is stated that "These "obs-" elements refer to tokens defined in the obsolete syntax in section 4. In all cases, these productions are to be ignored for the purposes of generating legal Internet messages and MUST NOT be used as part of such a message." As the comment deals with *generating* a date time string as part of a format, it is invalid to mention those obsolete timezones specifications. The nonterminals in the 2822 rfc starting with "obs-" are obsolete parts of the old (RFC 822) standard. We state in the manual (http://no2.php.net/timezones) which time zones we support, and "UT" is not one of those. First of all those timezone names from from a standardized timezone database, and secondly, UT would be semantically wrong as is explained in bug #42486. Previous Comments: ------------------------------------------------------------------------ [2008-05-04 08:30:13] selsky at columbia dot edu Description: ------------ strtotime() does not recognize the timezone "UT". According to RFC 2822 and the comments in ext/date/php_date.c (line 384), the valid time zones are: * zone = "UT" / "GMT" / "EST" / "EDT" / "CST" / "CDT" / "MST" / "MDT" / "PST" / "PDT" / 1ALPHA / ( ("+" / "-") 4DIGIT ) UTC is correctly recognized. http://bugs.php.net/bug.php?id=42486 was closed as won't fix, but this means we can't parse valid rfc2822 strings. Reproduce code: --------------- <?php print strtotime('12 Sep 2007 15:49:12 UTC') . "\n"; print strtotime('12 Sep 2007 15:49:12 UT') . "\n"; Expected result: ---------------- 1189612152 1189612152 Actual result: -------------- 1189612152 [blank] ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44909&edit=1
