As I understand it, the system clock is set upon boot from network time sources by the command /etc/init.d/ntp start and can subsequently be set by /etc/init.d/ntp restart
NTP is a process that continually keeps your system clock in sync with a higher level clock. Read up on it here: http://www.ntp.org/ or http://ntp.isc.org/
There's a "drift file" that is used in order to update the clock hourly, though its explanation isn't entirely clear.
http://www.eecis.udel.edu/~mills/ntp/html/build/quick.html : "During operation ntpd measures and corrects for incidental clock frequency error and writes the current value to a file called by default /etc/ntp.drift"
The problem I'm having is that my clock drifts noticeably, possibly because the drift file has bad data.
what does "ntptrace" say? It sounds more like your clock isn't in fact being synchronised. /Per Jessen, Zürich -- http://www.spamchek.com/ - managed anti-spam and anti-virus solution.
