[BlueOnyx:04081] Re: NTP etc

[Jason Ozin]

And to further answer and refine my answer this is what was needed in
crontab
In case anyone is interested, this clock drift is a known issue when
virtualising BlueOnyx/Linux on VMWare or Hyper-V 

# update clock every 30 mins
10,40 * * * * /usr/sbin/ntpdate -s -b -u pool.ntp.org
# sync hardware clock 5 mins later
15,45 * * * * /sbin/hwclock --systohc

To answer my own question I think this will work so I have done it:

Added this to the crontab for root:

   # update clock every 15 mins
   15 * * * * /usr/sbin/ntpdate -s -b pool.ntp.org

I've just logged in to one of my servers to find that the time is 14 mins
out. Going to System Settings/time and clicking save gives me the correct
time.

I assume that submitting This page obviously restarts one of the services
and thus gets and resets the time.

I also assume that there is a cron job or similar that is supposed to be
doing the same?

So how do I check it is working and if it is, where do I reduce its schedule
so as to cause it to update more often?

Many thanks is advance

Jason
