Documented that '24:00' is unsupported prior to 5.3.0. ------------------------------------------------------------------------ [2010-02-18 14:16:31] mike dot turpin at gmail dot com I did originally point out the problem as a suspected documentation bug. Could the documentation point out this? ------------------------------------------------------------------------ [2010-02-18 14:14:28] mike dot turpin at gmail dot com -Status: Bogus +Status: Open Just to point out that I actually found this in version 5.2.11 but don't want to upgrade yet as my web host uses this version. ------------------------------------------------------------------------ [2010-02-18 14:14:11] derick@php.net -Status: Open +Status: Bogus This is not a bug, the following happens in 5.2: strtotime( "24:00" ) returns "false" (because 24:00 is not supported) date() uses an integer representation of false (0) and then formats it using the current timezone: php -r 'echo date(DateTime::ISO8601 . " e", 0), "\n";' 1970-01-01T01:00:00+0100 Europe/London (Yes, on Jan 1st 1970, London had an offset of UTC+1, search for "British Standard Time Act 1968 (1968 c. 45)" at http://www.srcf.ucam.org/~jsm28/british-time/) In PHP 5,3, "24:00" is supported and the following happens: derick@kossu:~$ php -r 'echo strtotime("24:00");' 1266537600 derick@kossu:~$ php -r 'echo date(DateTime::ISO8601 .
