Nice descriptive article. I've done this on purpose too to debug remote filesystem syncs and cryptography problems where machines are out of sync. My GPS wall clock is handy for adjusting NTP, but the time it takes to scan my eyes from the wall back to the monitor.. you really do need two stacked like she did. So I now figured to use transparrent terminals each logged into a different host and lay them over one another running "watch -n1 date".

Would have been nice to have some more network, code and command line examples. You need to set up a local ntpd and need to point your local master at that temporarily. A better utility to write would be "timediff -s1 -s2" that takes two time servers and shows the offset. I bet there's a way to do that in one line. Anyone?

I’m not sure I get the fifty years bit at the very end. Anyone care to explain?
