Module Name:
DATETIMEPARSER.CPP
Abstract:
Parses a date/time string and converts it into it's component values.
History:
raymcc 25-Jul-99 Updated to bypass strict checks on DMTF
formats due to backward compatibility issues
and breaks reported by other teams. See
NOT_USED_IN_WIN2000 #idndef bracketed code.
