So, I've tried digging around the XML files, to no avail, but what I wanted to do is change the date stamp so that it would progress by a month every turn instead of a week. Cause the progress we see in terms of a year (multiplying populations, massive expansion, etc.) does not seem realistic for one year. 

So I wanted to change the timestamp so that twelve turns would be a year, indicated by the date.

To be clear, I want to change the timestep, not disable it, I know I can do that, but I am branching out (or trying to) my modding abilities, but I cannot find what dictates the timestep   

I know this is a little thing, but I wanted to see if anyone knew how.
