[OT] your clock, was Re: Verify a mirror?

[David Wright <deblis@lionunicorn.co.uk>]

Your clock appears to be fast by the precise number of seconds it took
for your post to leave your computer and reach my mail server.

That's the output of a tiny script that I was just tweaking, that
uses sed to extract the times from the first Received: header and
the Date: one.

I have mutt keys that print the UTC or Local (mine) post time, but
was just adding one to measure the transit time for tardy postings.
I tested it on a random post (yours—it's short), and was worried
for a moment that it was matching the wrong lines. But no, it's
your clock.

sed -n -e '/^[[:space:]]\+for <.*lionunicorn.co.uk>;/{s/.*; /Arrived: /;p};/^Date: /{s/Date: /Poste\
d:  /;p}'

for anyone who's wondering.

Cheers,
David.
