Re: [Linuxptp-users] Offset between TAI and PHC

[Dennis H. (dehagart) <deh...@ci...>]

Hi,

Yes, I think so.

The GM will send those values in the Announce message and you pick it up with -w
If it's not, you can configure the offset locally on the client end with -O

Dennis

I think you need to set currentUtcOffsetValid and timeTraceable on the
GM with a pmc SET GRANDMASTER_SETTINGS_NP command for the client's
phc2sys to actually set the TAI-UTC offset of the system clock.
