/usr/bin/exim_msgdate

Usage:
    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 ...]

    exim_msgdate --help|--man

Options:
  Time Zones and Unix Time:
    -u | --unix
        Display time as seconds since 1 Jan 1970, the Unix Epoch.

    --GMT -u|--UTC -z|--zulu
        Display time in GMT/UTC - we assume these are the same. Zulu time is
        another name for GMT.

    -l | --local
        Display time in the local time-zone.

        Do not confuse this with the --localhost_number option.

    The default is the local timezone.

  User Assistance Options:
    --help
        A brief list of the options

    --man

    --debug
        Information about what went wrong, mostly for developers.

  Specialized Options:
    --base n | --base36 | --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 "exim"; in this installation it is base-62.

    --pid
        Report the process id as well as the date and time in the
        message-id.

    --localhost_number n
        If the Exim configuration option 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).
        "Exim_msgdate" reads the Exim config file (see --C) 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 --local option, which displays times in
        the local timezone.

    --C full path to exim configuration file
        This overrides the usual exim search path. We set "localhost_number"
        from the exim configfile.

    -dexim_path
        The test harness passes the full path of the "exim" binary, or here
        the "exim_msgdate" being tested. Not currently used.
