[Linuxptp-users] Running ptp4l using UTC timescale with hardware time stamping

[Koehrer M. (ETAS/ESW5) <mat...@et...>]

Hi all,

we want to synchronize a couple of PCs. These PCs have to run for a couple of hours in a synchronized way.
We do not have a proper grandmaster clock, one of the PCs plays this role.
We use suitable Ethernet adapters (Intel IGB driver) to use the hardware time stamping.
In this setup the usage of the separate PTP time scale (with the offset of 35s against UTC) is really confusing.
Is it possible to force ptp4l to use UTC also for hardware time stamping e.g. by using an option (in the config file)?

That would ease everything dramatically!

Thanks for any hints on that!

Regards

Mathias
