This also can be helpful during scenarios where the GMS servers end up not following current UTC time, as players will be able to notice that the GMS servers are behind/forward an hour due some event such as daylight savings. After which, players can inform the GMS team, and can continue performing their dailies using the time shown in-game.

Do you know whether the monthly cap is 45k like Rexaar said or lower? Like me, V13T and I both haven't reached 45k for the month. In fact, I haven't even reached half of that. V13T's monthly total is around 30k whereas mine is near 21k.
I also started having the same problem starting yesterday. Not sure how the monthly cap works bc mine calculated to around 55k for this month and when I read the Limitations in the Maple Rewards Points UI, it says "You can earn up to 200,000 points per account per month." I recommend you submit a ticket if you haven't already just incase.
