Parameters
----------
template : DateTemplate or str
Can be either a `DateTemplate` instance, or a string which will
be used as the pattern for the `DatePatternRegex` template. The
template will then be added to the detector.
Raises
------
ValueError
If a template already exists with the same name.

This uses the templates' `matchDate` method in an attempt to find
a date. It also increments the match hit count for the winning
template.
Parameters
----------
line : str
Line which is searched by the date templates.
Returns
-------
re.MatchObject, DateTemplate
The regex match returned from the first successfully matched
template.

r� q� Xn d S( s Attempts to return the date on a log line using templates.
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.
