All PHP-based timestamp/synchronization services inside the /time URL path, including https://currentmillis.com/time/minutes-since-unix-epoch.php, have been marked for deprecation and sunset, i.e. removal. All these aforementioned PHP services have been, for a while now, setting the following response headers:
Deprecation = @1794394800
Sunset = Wed, 11 Nov 2026 11:11:11 GMT
This means, effectively, that at any point in time after November 11, 2026 the mentioned services may and will stop functioning.
As a potential replacement, with a better resolution (at seconds level), but with a different format/paradigm, the new "beacon" can be used. Effectively, this is a new, lightweight endpoint designed for HEAD or GET requests. Here is the latest version of this beacon:
Current Millis V2 Time Beacon
The paradigm shift implies relying on multiple sources of truth and calculating the best approximation of the current time based on the available sources of truth. One such source, in this case, can be the Date response header returning the current time in IMF-fixdate format from the currently available beacon, but in time, multiple beacons (and multiple types of beacons/endpoints) may become available. Stay tuned!
