Hello Yvonne,

I use one of the following two commands (depending on what is available)
to initially set the system clock prior to installing either Transarc or 
OpenAFS on Linux:

a) rdate -s ntptimeserver.wherever.domain
b) ntpdate -u ntptimeserver.wherever.domain

This is followed by: hwclock --systohc

Subsequently, running ntp daemon keeps the clock in sync wth ntp servers.

If you only rely on using the ntp daemon, the problem is that the delta 
adjustments
are very small and it could takes a long time (depending on how skewed 
your clock is)
to get in sync.

I hope this helps.
