> Independent, community-run public NTP time server for the Kingdom of Bahrain, with a live dashboard of server metrics, Manama weather, WBGT heat-stress index, tides, and a Bahrain calendar. This is NOT an official or government service.

## About

- clock.bh is a free public NTP (Network Time Protocol) server located in Bahrain, operated by an individual as a community service. It is not affiliated with the government of Bahrain.
- NTP endpoint: `clock.bh` over UDP port 123 (IPv4 + IPv6), served by chrony, stratum 2, syncing to multiple upstream sources.
- The website shows: the current time in Bahrain (Asia/Bahrain, UTC+3), live NTP server metrics (unique clients, requests/sec, stratum, offset, jitter, root delay, uptime), Manama weather, a computed WBGT heat-stress estimate, tide predictions, and a Bahrain calendar with public holidays and Hijri dates.
- All metrics are real measurements from the local chrony daemon. WBGT and tide heights are clearly labelled estimates (energy-balance model / ocean model).
