I wanna move from Adamantoise to Tonberry for my friends. but system says I can't...

It says
- This character cannot use the World Transfer Service until 90 days have elapsed since the character was created. Please try the process again after 90 days have elapsed.

But i created my character 4 months ago, about more than 120 days.

I don't know how system counts this limitation days..

thx for your help.
