Milliseconds Resolution

[Fairlight]

Which simplicity neglects a few of the gotchas, such as needing the command
to -not- be variable in nature.  I recall that being a limitation.

You also don't -need- to feed it input, unless it needs input.  If it's
just getting a timestamp, that's a single read and then close the alias.

USER is a bit odd though, yeah.
