I need to check for a clock skew in many remote machines. What is the best way to check for a clock skew on a Linux machine?
I don't need to sync clocks, just to check how accurate it is. I don't have root on those machines. I don't have direct access there, I just can submit jobs there. I think all machines have NTP configured, but could use different servers.
I need to write a simple, robust bash script for that.
