You have to use phc2sys to synchronize the masters PHC clock to the masters
system clock. I'm not sure but I think it also has to be used on the slave
side to synchronize the slave system clock to the slave PHC clock, Richard?

Subject: Re: [Linuxptp-users] Trying to sync date between master and slave
Hello Richard,
I didn't get why you are suggesting to run phc2sys in master ??
Would like to say my requirement once again,
Master side Slave
side
system clock-->PHC clock---------------------PHC clock--->system clock
Master:
1) setting date:
Wed Jul 24 10:08:00 IST 2019
2) Running :
./ptp4l -i eth1 -m
Slave :
1) setting date:
Wed Jul 24 10:09:00 IST 2019
2) Running :
./ptp4l -i eth1 -s -m
After running ptp4l utility in master and slave, i can see slave PHC clock is
synchronized with master.
Further more, i want to sync slave system clock with slave PHC clock which is
already synchronized above, so that i'm expecting slave date will become same
like master. (correct me if its not possible)
Kindly let me know after ptp4l what i need to run in slave to get my
requirement done.
Thanks,
Gourav

Hi,
If your intent is to serve the system time, then you need two -r flags
here, for example:
./phc2sys -a -r -r -m
the above said where i need to run in master or slave side ??
On the master (the one serving the time).
HTH,
Richard
