One of the keys to synchronization in the Client Tool is an accurate comparison of data between the Client Tool and EPA Host System. The synchronization process compares dates and times recorded on the EPA Host System with dates and times recorded in the Client Tool database to determine if data need to be synchronized to the Client Tool.

Until the 2009Q1 reporting period, we had not run into a problem related to time zones. The basic synchronization process took into account time zones by, for data comparison purposes, adjusting the time to account for the possible time zone difference between the EPA Host System which is in the Eastern time zone and the Client Tool which could be in any time zone. However, a few shared database users found synchronization problems when multiple users in different time zones were connecting to the shared database. They found that no matter what, the data were always considered to be out of sync.

This problem, which was only found with the shared database and Client Tools in different time zones, will be corrected in the Service Pack 2 release scheduled for June 16th. The solution involves using Coordinated Universal Time (UTC) as the standard for all date and time comparisons. If you have any questions about this bug fix, contact Technical Support.
