[GT] Date format

["Weigert, Thomas" <weigert AT mst.edu>]

In DB/Text.pm it is stated that any date format understood by
Date::Manip is supported. However, the routines in
GT::DateTime::Day::date_to_time and similar in the other DateTime
modules insist that the dates are stored in the YYYY-MM-DD format.

It appears that there was an attempt to support more flexible date
parsing via GT::Tools::parse_date_str but I cannot see any usage of
that.

Is the repository outdated with respect to date parsing, or is the
documentation incorrect and this has not been implemented yet?

What is the status of GT::Tools::parse_date_str?

Please advise, Th.
