You need -r twice if you want the Linux system time to be the source:
-r Only valid together with the -a option. Instructs phc2sys to
also synchronize the system clock (CLOCK_REALTIME). By default,
the system clock is not considered as a possible time source. If
you want the system clock to be eligible to become a time
source, specify the -r option twice.
