Admin users now have the option to configure the time zone of the FIX session reset times. The field TimeZone under the FIX Session setup supports for time zone values consistent with the Olson database. This feature will eliminate the task of updating the session reset times every spring and fall.

All reset times currently in setup are unchanged and remain in UTC. Hence, there will be no impact to the ongoing session setups.

After the release, the users can update the time zone and reset times based on user preference.
