5.3.0 mktime() now throws E_DEPRECATED notice if the is_dst parameter is used. 5.1.0 The is_dst parameter became deprecated. Made the function return FALSE on error, instead of -1. Fixed the function to accept the year, month and day to be all passed as zero. 5.1.0 When called with no arguments, mktime() throws E_STRICT notice. Use the time() function instead. 5.1.0 Now issues the E_STRICT and E_NOTICE time zone errors.
