This uses the templates' `getDate` method in an attempt to find a date. For the faster usage, always specify a parameter timeMatch (the previous tuple result of the matchTime), then this will work without locking and without cycle over templates. Parameters ---------- line : str Line which is searched by the date templates. Returns ------- float The Unix timestamp returned from the first successfully matched template or None if not found.
