Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The parser tries to figure out what you're trying to do. That fails in the first instance: php -r 'print_r(date_parse("1423122337"));' Array ( [year] => 1423 [month] => 12 [day] => 23 [hour] => [minute] => [second] => [fraction] => [warning_count] => 0 [warnings] => Array ( ) [error_count] => 2 [errors] => Array ( [8] => Unexpected character [9] => Unexpected character ) [is_localtime] => ) But succeeds in the second: php -r 'print_r(date_parse("1738598400"));' Array ( [year] => 8400 [month] => [day] => [hour] => 17 [minute] => 38 [second] => 59 [fraction] => 0 [warning_count] => 0 [warnings] => Array ( ) [error_count] => 0 [errors] => Array ( ) [is_localtime] => ) Previous Comments: ------------------------------------------------------------------------ [2015-02-05 09:42:56] wanting_e at 163 dot com Description: ------------ I passed two different timestamp to strtotime() function.
