Regardless of your geographic location, you should probably use the standard server rotation provided by the NTP Pool Project.

The precision of curby.net time servers is generally 1-2 μs. Accuracy (offset) is generally within 1-2 μs for stratum 1 servers and 1 ms for stratum 2 servers.

In contrast, the live clock on this page is intended as an informal time of day service, and not for rigorous timing or clock synchronization. (more info)

The NTP Pool scorecard has recent performance data.

Accurate timekeeping is critically important to the Internet, but it doesn’t receive much support.

If you’d like to help, you can donate to the Network Time Foundation, a 501(c)(3) non-profit organization that supports network timekeeping projects such as NTP.

System administrators can add their servers to the NTP Pool.
