My Reference server is 13 mins fast. It's supposed to get time from the
internet and I will need to find out why the time source isn't working.

I have 1 Reference server, 6 Primary servers and 60+ Secondary servers.

My question is how should I adjust the time on the Reference server.
Most things I see say to set time back you must then declare a new
epoch. If I correct my Internet time source and restart timesource flag,
would this make the correction? Do I need to declare a new epoch?

Thanks for any help.
