FIX Services

US Daylight Savings Time begins on March 10 at 3am Eastern/2am Central time.
TT FIX services automatically reset weekly on Saturdays at 22:00 UTC. 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 also configured in UTC. If users desire to maintain the same daily reset time relative to their local timezone, 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.
