DateTime::Format::Mail - Convert between DateTime and RFC2822/822 formats
RFCs 2822 and 822 specify date formats to be used by email. This module parses and emits such dates.
RFC2822 (April 2001) introduces a slightly different format of date than that used by RFC822 (August 1982). The main correction is that the preferred format is more limited, and thus easier to parse programmatically.
