[ale] line timestamp command

[Ed Cashin]

I do happen to know of one, but it's by Dan J. Bernstein.  That sometimes
means it's of uncommonly high quality and careful design but low user
convenience.

Usually the resolution is to do everything the way DJB thinks things should
be done.  Then it's convenient and reliable.  But it requires the user to
adjust behavior and/or expectations.  In this case, tai64n does what you
ask for, but the timestamp is not probably anything you'd want to read.  So
tai64nlocal converts it.  Weird, but not carelessly designed.
