S( s� Sets regex to use for searching for date in log line.
Parameters
----------
regex : str
The regex the template will use for searching for a date.
wordBegin : bool
Defines whether the regex should be modified to search at beginning of a
word, by adding special boundary r'(?=^|\b|\W)' to start of regex.
Can be disabled with specifying of ** at front of regex.
Default True.
wordEnd : bool
Defines whether the regex should be modified to search at end of a word,
by adding special boundary r'(?=\b|\W|$)' to end of regex.
Can be disabled with specifying of ** at end of regex.
Default True.

This should return the date for a log line, typically taking the
date from the part of the line which matched the templates regex.
This requires abstraction, therefore just raises exception.
Parameters
----------
line : str
Log line, of which the date should be extracted from.
default_tz: if no explicit time zone is present in the line
passing this will interpret it as in that time zone.
Raises
------

Parameters
----------

instead.
