""" This module provides a set of constructors and routines to convert
    between DateTime[Delta] instances and ARPA representations of date
    and time. The format is specified by RFC822 + RFC1123.

Note: Timezones are only interpreted by ParseDateTimeGMT(). All
    other constructors silently ignore the time zone information.
