This question already has an answer here:
I have written a Puppet module that corrects the time via NTP, but this only works on server with a small NTP offset.
There are sometimes server with a time offset higher than 10 minutes for various reasons.
I want to make a Puppet module that runs exec "service ntpd stop; ntpdate ntp3.domain.local; service ntpd start" when the ntp offset is too high, to forcably correct the time.
How can I see if the NTP offset is too high in order to tell Puppet to run this command? Or are there better solutions?
