PTP v1
The Precision Time Protocol (PTP) is used for clock synchronization over the
Internet. It has clock accuracy in the sub-microsecond range, making it more
granular than NTP.
NTP sends UDP packets over port 123 on Pearl-2 and PTP sends UDP packets over ports 319 and
320. If Pearl-2 is behind a firewall, you must open these ports to allow traffic when Pearl-2 is
configured to use either an NTP or a PTP server to obtain its time and date information.
