nice job, Lee.
Note that NIST:
http://tf.nist.gov/tf-cgi/servers.cgiis recommending ntp as replacement for the old "DAYTIME" protocol
thus:
(setq server
"ntp://time.nist.gov/");newer protocol
works here.
@ mailmaverick:
yes, true enough.
by default, though, Windows systems are set to sync with a time server
so, it takes a conscious act to de-sync system time,
which would result in all local time stamps becoming inaccurate.
Is it likely someone would do that, just to run an expired AutoLISP demo?
I think not, but perhaps I am mistaken.
In any case, locks only keep out the honest folks.
