A public IPv4 NTP service from WW.CX, independently monitored from an external network. The clock at right is displayed as UTC / GMT+00:00 and is anchored to the latest external WW.CX NTP observation whenever that observation is fresh.

For important systems, use several independent time sources rather than depending on any single public server. NTS adds cryptographic authentication to supported clients; the service has completed an authenticated Internet-side acceptance test while independent external monitoring continues recurring standard-NTP observations.

The WW.CX public time service is presently disciplined by a nearby ISNIC GNSS-backed Stratum-1 reference; the externally observed served stratum is shown live. The canonical name is ntp.ww.cx. time.ww.cx is an alternate public name for the same service.

External network
An independent external monitor periodically checks the public service and publishes only bounded health metadata.
Check the server without changing the system configuration:
w32tm /stripchart /computer:ntp.ww.cx /samples:5 /dataonlyAdd WW.CX as one source among several:
server ntp.ww.cx iburstUse the authenticated NTS endpoint:
server ntp.ww.cx iburst ntsStandard NTP is also published at:
time.ww.cxThe WW.CX public time service answers NTP requests. A separate external monitor periodically queries the public endpoint. The webpage uses the observer’s measured clock offset to estimate current WW.CX time, then advances it locally with a monotonic browser timer between refreshes.
Precision note: this web clock is for convenient human display. Browser rendering, HTTP latency and observer age mean it is not a laboratory reference. Software that needs synchronized time should use NTP or NTS directly.
WW.CX Time is a best-effort public Internet time service. It is not a legal-metrology, navigation, medical, emergency, industrial-safety or other life-safety reference. Critical systems should use multiple independent sources and appropriate local holdover and monitoring.
