# realtime var (world)

Source: https://ref.dm-lang.org/world/var/realtime

This is the time (in 1/10 seconds) since 00:00:00 GMT, January 1, 2000 (also known as the BYOND era).

Because this is a large number, BYOND's number system isn't capable of enough precision to deliver the exact number of 1/10 second ticks. It usually rounds off to the nearest several seconds. For more accurate readings use `world.timeofday`.
