Oh, is it expected behavior ?

Is there any option to run both the clock on either UTC/TAI timescale ?

No, I am not running phc2sys on MASTER. But if I run phy2sys on master
side (phy2sys -s /dev/ptp0 -w), then,

a. Both MASTER and SLAVE system time will synchronize but I am seeing
same 25-30sec difference between PHC and SYSTEM time on both MASTER
and SLAVE.

b. Both MASTER and SLAVE PHC are in sync.
