Description
The command parses dates according to the ARPA Internet standard. It
also understands many non-standard formats, such as those produced by
TOPS-20 sites and some UNIX sites using It is useful for seeing how MH
will interpret a date.
The program treats each argument as a single date, and prints the date
out in the official RFC 822 format. Hence, it is usually best to
enclose each argument in double quotes (") for the shell.
