So date_create_from_format('m-d-Y H:i:s T', $dateTime->format('m-d-Y H:i:s T')); will generate an error. should read: So date_create_from_format('m-d-Y H:i:s.u T', $dateTime->format('m-d-Y H:i:s.u T')); will generate an error. ------------------------------------------------------------------------ [2008-07-18 11:28:52] tj at systisoft dot com Upsi, there should be 6 zeros in the microsecond part of the expected result. ------------------------------------------------------------------------ [2008-07-18 11:26:24] tj at systisoft dot com Description: ------------ The u format char behaves inconsistent. 1. In output the it uses 6 digits. When used in date_create_from_format it recognizes only up to 5 digits (though microseconds would be 6). So date_create_from_format('m-d-Y H:i:s T', $dateTime->format('m-d-Y H:i:s T')); will generate an error. 2. Though DateTime does not support microseconds (or does it?) and should cut them off it behaves very strange when parsing a date with fractional seconds. Reproduce code: --------------- $d = date_create_from_format("m-d-Y H:i:s.u T", "03-15-2005 12:22:29.00000 PST"); echo $d->format("m-d-Y H:i:s.u T"); $d = date_create_from_format("m-d-Y H:i:s.u T", "03-15-2005 12:22:29.00100 PST"); echo $d->format("m-d-Y H:i:s.u T"); Expected result: ---------------- 03-15-2005 12:22:29.00000 PST 03-15-2005 12:22:29.00000 PST Actual result: -------------- 03-15-2005 12:22:29.000000 PST 03-15-2005 12:22:29.100000000 PST ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45554&edit=1
