Hi,
I don't think that one is quite right... Your optionals (?) are confusing. Why [0-3]?[0-9] AND the \d?
No reason.
Why [0-9] at all (since \d is essentially [0-9])?
Again, no reason.
Why use the discarded capture group (?:) since the [0-3] is already optional?
It makes it look more like gibberish?

hate to say this but why not cater for all eventualities and just use strtotime( $whatever );
