Internal Program Version: DateTime::Format::Strptime  1.800.0.5.42.0

This module implements most of 'strptime(3)', the POSIX function that is
the reverse of 'strftime(3)', for 'DateTime'. While 'strftime' takes a
'DateTime' and a pattern and returns a string, 'strptime' takes a string
and a pattern and returns the 'DateTime' object associated.
