# realtime for OpenComputers Given the lack of a good way to get the real-world time from an OpenComputers machine, the *realtime* library and protocol were created. ## OpenOS The realtime package for OpenOS includes: - The [realtime library](OpenOS/usr/lib/realtime.lua) itself, for OpenOS - [realtime-sync](OpenOS/etc/rc.d/realtime-sync.lua), for synchronising with the real world - [realtime-relay](OpenOS/etc/rc.d/realtime-relay.lua), for synchronising with another OpenComputers machine These can be installed as oppm packages, and documentation can be found [here](OpenOS/usr/man)
