How do I set my server to UTC/Zulu time for the engine?

The engine requires PHP 7.4.x and the server clock set to UTC/Zulu time. This is not optional — all drop times are expressed in Zulu, so if your server runs on a local timezone the engine will fire at the wrong moment and you will lose catches.

On your Linux server, set the system timezone to UTC before running the engine. Once set, everything the engine reports and every create it fires is aligned to Zulu, matching Nominet's published drop times.

Check this first if catches that should be winnable are consistently missing — a clock on the wrong timezone is a common, easily fixed cause.
