New constants in DateTime

Hello internals, A similar question should have been asked already but I haven't found anything so far when googling: I think DateTime class should have the following constants in addition to those already existing: const SQL = "Y-m-d H:i:s"; const SQL_DATE = "Y-m-d"; const SQL_TIME = "H:i:s"; const SECOND = 1; const MINUTE = 60; const HOUR = 3600; const DAY = 86400; Easy-to-make feature that will be useful to a lot of PHP devs, I believe. The exact naming of SQL_* constants is subject to dsicuss. Best regards, Victor -- Best regards, Victor Bolshov
