Does Ignition have a functionality to determine the datetime of gateway startup and shutdown?

There is a system gateway tag called UptimeSeconds which you can use to infer the startup time. The shutdown time you could approximate as when the uptime was 0 i suppose.

You could also log to a db table using gateway startup and shutdown events.
