Date field in email notification is offset by -10 hours

Hi,We are experiencing an issue where email notifications which contain date fields are incorrect and is usually offset by -10 hours. For example, user enters 10/28/2014 12:00:00 AM for "Est Date" but the email notification delivers it as: Est Date: 10/27/2014 02:00:00 PM. This has just recently started happening but I'm not able to figure it out. I've edited User Profile>Time Zone to (GMT - 10:00) Pacific/Honolulu but email still sends the date wrong. Any suggestions what could be wrong? Thanks in advance!
