Suppose I want to compare log file on several systems. Assume they are all on
the same Ethernet switch. I'd like the clocks to track -- I don't care (much)
how accurate they are as long as they all have the same offset/error.
Has anybody worked on this area? (Is it simple enough not to requir

You could try PTP. The linuxptp project is active. With ethernet cards
that support hardware time stamps you can get 1 micro second offsets, maybe
a lot better.

NTP can make use of some of the features that PTP hardware supports.
