Re: [PATCH] selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET

Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful.

This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value.
