I agree, that some clarification in the manual is in order. Previous Comments: ------------------------------------------------------------------------ [2012-03-07 09:14:54] mwwaygoo at hotmail dot com Description: ------------ --- From manual page: http://www.php.net/function.strtotime --- Specifying a date of 10-11-77 will epoch, and not create the timestamp for 10-11-1977 as expected, according to the two notes on the strtotime() function page shown below. This should really say "whereas if the separator is a dot (.), then the European d.m.y format is assumed" Note: If the number of the year is specified in a two digit format, the values between 00-69 are mapped to 2000-2069 and 70-99 to 1970-1999. Note: ...whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed. Test script: --------------- echo date("Y-m-d H:i:s", strtotime("10-11-77 03:12:01")); // unexpected fail: supposed to be d/m/y with year 77 auto changed to 1977 echo date("Y-m-d H:i:s", strtotime("10.11.77 03:12:01")); // pass: EUR d/m/y with year 77 auto changed to 1977 echo date("Y-m-d H:i:s", strtotime("10/11/77 03:12:01")); // pass: US m/d/y echo date("Y-m-d H:i:s", strtotime("77-11-10 03:12:01")); // pass: ISO 8601 y-m-d echo date("Y-m-d H:i:s", strtotime("77/11/10 03:12:01")); // expected fail: US m/d/y data incorrect Expected result: ---------------- 1977-11-10 03:12:01 1977-11-10 03:12:01 1977-10-11 03:12:01 1977-11-10 03:12:01 1970-01-01 00:00:00 Actual result: -------------- 1970-01-01 00:00:00 1977-11-10 03:12:01 1977-10-11 03:12:01 1977-11-10 03:12:01 1970-01-01 00:00:00 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61314&edit=1
