First it depends on single player or multiplayer. Then it depends on how you approach the game as a GM meaning will you be a gambler or play it cool. Being a GM takes time just like the real gm's are. There are so many things that a GM has to do in making decisions. A true GM never rests at all he constantly works 24/7. If you want to be a great well known GM then you will have to work very long hours. There's always something that a GM has to do. The daily time for a GM greatly depends on how successful you want the team to succeed in winning that Championship trophy. That pretty much sums it up.
