BBMS processes all gifts in Eastern Standard Time (EST) only, even if the database is in your local time zone. This cannot be changed or edited.

Even if a transaction is processed after 11:59 PM EST, the date and timestamp in BBMS will be reflected in EST. To prevent transactions from having a different date than the database, they need to complete processing by 11:59 PM EST. If you are running a large batch, ensure the batch is submitted with enough time to complete prior to midnight EST for same day results.
