I have problems with putting it in minecraft can someone help me with that? I got an timer from mega but how to put in minecraft?

And i see that gamma must be below 5? but is that render distance or brightness??

gamma is brightness

You don't put the timer in minecraft, you just open it.

Also you shouldn't be using the one from mega unless you're running pre-1.7 obviously

Also gamma is brightness, so if your in-game brightness is 100% then that is gamma 1. We allow people to change the options files to up to gamma 5 for bad monitors

I opened it but i have no clue where the timer is?
