$ rsh filer options | grep timed
timed.auto_adjust            off        
timed.enable                 on         
timed.log                    off        
timed.max_skew               30m        
timed.min_skew               1          
timed.proto                  ntp        
timed.sched                  10m        
timed.servers                guinness   
timed.window                 0s

By default, timed.proto is rtc which means the clock will differ from the rest of the world.

These are the recommended settings:

$ rsh filer options timed.enable on
$ rsh filer options timed.proto ntp
$ rsh filer options timed.min_skew 1
$ rsh filer options timed.sched 10m

Notes:

  • the documentation does not state what unit min_skew is defined as. The default is 50.
  • timed.auto_adjust and timed.window are similarly undefined.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.

Useful:
