+=head1 NAME
+
+  exim_msgdate -  Utility to convert an exim message-id to a human readable date+time
+
+=head1 SYNOPSIS
+
+B<exim_msgdate> [ -u|--unix | --GMT | --z|-Zulu | --UTC | -l|--local ]
+      [ --base 36 | --base 62 | --base36 | --base62 | --b36 | --b62 ]
+      [ --pid ] [ --debug ] [ --localhost_number ]
+      [ -c c<full path to exim cnfig file> ]
+      exim-message-id [ | exim-message-id ...]
+
+B<exim_msgdate> --help|--man
+
+=head1 DESCRIPTION
+
+B<exim_msgdate> is a tool which converts an exim message-id to a human
+readable form, usuall just the date+time, but with the I<--pid> option
+the process id as well.
+
+=head1 Message IDs:
+
+Three exim message ID formats are recognized.
+In each case the 'X's are taken from the base (see below) which depends upon the platform.
+
+=over 4
+
+=item XXXXXX-XXXXXX-XX
+
+found in the exim logfile,
+
+=item EXXXXXX-XXXXXX-XX
+
+found in the Message-Id header,
+
+=item XXXXXX
+
+just the first six characters of the message id.
+
+=back
+
+=head1 OPTIONS
+
+=head2 Time Zones and Unix Time
+
+=over 4
+
+=item     B<-u | --unix>
+
+Display time as seconds since 1 Jan 1970, the Unix Epoch.
+
+=item     B<--GMT> B<-u|--UTC> B<-z|--zulu>
+
+Display time in GMT/UTC - we assume these are the same.
+Zulu time is another name for GMT.
+
+=item     B<-l | --local>
+
+Display time in the local time-zone.
+
+Do not confuse this with the L<--localhost_number|/--localhost_number-n> option.
+
+=back
+
+The default is the local timezone.
+
+=head2 User Assistance Options
+
+=over 4
+
+=item     B<--help>
+
+A brief list of the options
+
+=item     B<--man>
+
+A more detailed manual for B<exim_msgdate>
+
+=item B<--debug>
+
+Information about what went wrong, mostly for developers.
+
+=back
+
+=head2 Specialized Options
+
+=over 4
+
+=item B<--base> n | B<--base36> | B<--base62>
+
+The message-id is usually encoded in base-62 (0-9A-Za-z),
+but on systems with case-insensitive file systems, such as MacOS and Cygwin,
+base-36 (0-9A-Z) is used instead.
+The installation script should have set the default appropriately,
+but these options allow the default base to be overridden.
+
+The default matches C<exim>; in this installation it is base-BASE_62.
+
+=item B<--pid>
+
+Report the process id as well as the date and time in the message-id.
+
+=item B<--localhost_number> n
+
+If the Exim configuration option B<localhost_number> has been set,
+the third and final section of the message-id will include this and
+the timer resolution will change (see the Exim Spec. for details).
+C<Exim_msgdate> reads the Exim config file (see L<--C|/C-full-path-to-exim-configuration-file>) to find this value,
+but it can be overridden with this option.
+
+The value is an integer between 0 and 16, or the value "none" which
+means there is no localhost_number.
+
+Do not confuse this with the L<--local|/l---local> option, which displays times
+ in the local timezone.
+
+=item B<--C> B<full path to exim configuration file>
+
+This overrides the usual exim search path.
+We set C<localhost_number> from the exim configfile.
+
+=item B<-dexim_path>
+
+The test test harness passes the full path of the C<exim> binary,
+or here the C<exim_msgdate> being tested. Not currently used.
