Solved Changing day and night cycle of my server?

I've used the RCON commands given from here: Server Commands - Play Rust Wiki
And I have RCON up and running but the commands env.daylength and env.nightlength are not found. Have they changed the names of the commands or am I typing them wrong? Also I couldn't find an oxide mod that changes this. Any help would be appreciated.

 

Thanks Wulf.
