Notice how almost all of them are port 123 on both sides, but a few of

NTP not using port 123 as the source port usually indicates that it is
behind a NAT gateway at the other end. It's harmless and fairly common.
...or simply that it is a ntp *client* like ntpdate, and not a daemon.
Clients often use a random source port, while ntpd use source port 123.
