Vooch: I have always played every day between 8 and 10 pm.
In which time zone are you?
Assuming you are on Eastern Time (EDT), it's a dangerous time, as midnight GMT happens at 8 pm EDT. Then, finishing before 8 o'clock would be playing in the former day and maybe missing a day. Other US time zones are safer because the new day in GMT comes earlier.
Vooch: I played tonight 10/18/15 and the date is showing 10/19/15.
There's a difference between tournaments and other ranked games. Some seem to be shown in GMT rather than PDT/PST.
Apart from the comfusion generated, it's not incorrect but shows that you may have missed the "good" time to play, either that night or the night before when you may have played earlier. Or, you failed to finalize the game.
Vooch: Please look into this and correct this as soon as possible.
IMHO, there's nothing to correct, and WGT never reinstalls the CDP number. You just have to take care of when you play and look for the green check mark.
BTW: One hole practice is enough!
