How do I place a map cycle?

[IniX]

Hey, I'm new to this program and have a question.
How do I place a cycle in the map? Such as that the map changes each 30 minutes?

mp_timelimit 30 // timelimit on each map

Put this in your server.cfg

To put more Time per map Change the 30 to what ever time you want, same for Shorter time
