[Koha] Date off

Evening all, I seem to be having a date problem. I've found the date ahead 1 day in two places. 1. I checked myself out a book. I then looked at my Circulation History. The column for date is one day ahead. the column for Checked out On" is the correct date. 2. Under Acquisitions, I added an item to a basket. Again the date entered was the next day. I've checked the server and the date and time are correct. Is there somewhere in one of the settings or a configuration file that specifies the date?? We are running Version 3.16.04 Running on an Amazon EC2 server Ubuntu flavored Linux system Thanks Jack Morash
