It's also convenient, if you have the correct time. Running 'make' to build larger
binaries, that span several NFS mounts can be a hog, if 'make' gets confused on the
timestamps of files on the various servers.
Silly thing, but guess, how long it took me to....... ;-)

Can't tell for the US, but I like my little external clock-device receiving the time signal, which
is in Germany called DCF-77. I configured NTP to use that device on one system and
synchronize the rest of the net to that system. The receiver device - connecting to a parallel port -
is well supported in linux and only US-$ 29. Again, this is for germany only, but i assume,
other countries have similar cheap offerings.
I prefer this over synchronizing to 'external' ( read; internet ) timeservers, since the communication
btw the timeserver and your local net can be hacked.

However, all of this wouldn't help Chris anyway. ntpd by default will not synchronize to an
external clock-source, if the drift between local clock and remote clock suddenly jumps
by a few years. ntpd will, in that case reject the external clock source as being valid.
Of course, you can configure ntpd to trust the external source more that the system's own clock,
but that *really* would open big hacking opportunities to hackers, if you synchronize to
internet-space timeservers ;-)

Anyway, CONFIG_RTC=y prevented my Alphas from skipping dates, as stated before.
If you run anything depending on file-times over network services. i strongly recommend
using ntpd and a nifty hardware-clock.

Although, I found ntp to be a real STRANGE thing to configure........

Am i off-topic ? yes. But ir's late and all of my beer is empty ;-)
