[chrony-users] Syncing time as with a single request

[Gustav Krantz <Gustav.Krantz@xxxxxxxxxxxxx>]

Hello all,

I’m trying to sync system time as quickly as possible as I have a time requirement to meet. Currently I’m using the iburst option against several servers, along with “makestep 1.0 3”, and a wait service that calls “/usr/bin/chronyc -h 127.0.0.1,::1 waitsync 600 0.1 0.0 1” to ensure that other services run only after the clock has been synced. This takes about 6 seconds.

 

If I want to sacrifice some accuracy to reduce the sync time, what would be best practice?

Would it be possible to do the initial sync with a single request per server? If so how would this be done and what would the drawback be?

Is editing the parameters of the wait-service an option, or will the iburst option always send at least 4 requests before the time is considered to be synced?

 

Any suggestions are greatly appreciated!

 

Thank you & kind regards,

Gustav
