[Linuxptp-users] utc_offset: how does it work? Does it work with SW TS?

[Elder Costa]

I ran a test with the system below. GM and AM running SW timestamp.
The System clocks of the SOM and the AM synchronize with the GM's but
there is an offset of 37s (GM's 37s ahead the other two). I tried
using --utc_offset on the ptp4l instance running in the GM with no
success: no matter the value, the offset stays in 37s. What am I doing
wrong?

System clock GM        +--> System clock SOM --+          System clock AM
