Protocol
- NTP protocol implementation
- Chrony and ntpd control protocol implementations
Leaphash
Utility package for computing the hash value of the official leap-second.list document
leapsectz
Utility package for obtaining leap second information from the system timezone database
ntpcheck
CLI and library to perform various NTP-related tasks, including:
- replacement for
ntptimeandntpdatecommands - human-readable diagnostics for typical problems with NTP based on data from chrony/ntpd
- server stats and peer stats taken from chrony/ntpd with output in JSON

checker
Package checker provides an easy way to talk to NTPD/Chronyd and get NTPCheckResult, which abstracts away Chrony/NTP control protocol implementation details and contains tons of information useful for NTP monitoring, like NTP server variables including offset, peers and their variables and statuses.
