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

A more detailed manual for exim_msgdate

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