WebNTP is a built-on UDP, where port 123 is used for NTP server communication and NTP clients use port 1023 (for example, a desktop). Unfortunately, like many legacy protocols, NTP suffers from security issues. It is possible to spoof NTP packets, causing clocks to set to various times (an issue for certain services that run periodically).
