FIX Services
U.S. Daylight Saving Time (DST) begins March 8 at 2:00 AM local time.
TT FIX services reset weekly on Saturdays at 22:00 UTC by default. If FIX sessions utilize the optional Reset Schedule in Setup to perform a daily reset or change TT's weekly default, please note that these times are configured in UTC. If users desire to maintain the same daily reset time relative to their local time zone, they may need to adjust the UTC time Reset Schedule in Setup.
For example, if a FIX client application configured a daily reset time in Setup to be performed at 22:45 UTC, the session would be reset at 16:45 CST prior to Daylight Savings Time going into effect. When DST begins, the reset would occur at 17:45 CDT if no action was taken to adjust the Reset Schedule.
FIX clients connected to FIX v291 or higher have the option to specify a time zone other than UTC in the Session Reset Schedule in Setup. Configuring a time zone other than UTC eliminates the need to adjust configuration for seasonal time changes.
