The AAPK server is set to UTC time which runs four hours ahead of Eastern.
All orders & other time related activities have to be standardized when stored in the database to specific time that we can use to keep everything in correct chronological order for calculations & such.
Ideally, the date/time displayed on sale invoices should probably be adjusted to the location of the seller. I'll see about making that happen when I get a chance.
We will likely maintain UTC time when calculating commissions, however. I'll try to make that more clear on the commission invoices.
The due date on commissions is extended to allow for any adjustments that need to be made because of non-paying buyers, returns, cancelled sales, etc.
