It's a stupid implementation that is implying to players "ooh sorry, you are playing too early, come back later" except it doesn't even give you an error so most people will think it is just broken.
If player retention is the goal of this you are going to have a horrible month with a lot of high profile highly rated games coming out this week and next week
A real sysadmin knows how to change the time.
If you make the same mistake while trying to make up for the previous one, you are doing something wrong.
As much as I'd love to say I offer consulting services, the scope of things broken is too large.
