Winter Time and Daylight Saving Time (DST) can significantly impact international trading schedules, market hours, and global communication. This FAQ aims to clarify the concept of DST, its effects on different markets, and what our trading team needs to be mindful of when handling tickets related to time changes.

Winter Time and Daylight Saving Time (DST)

1. What is Daylight Saving Time (DST)?
   DST is a system where clocks are moved one hour forward in spring ("spring forward") and one hour back in autumn ("fall back") to maximize daylight during working hours. Not all countries observe DST. This impacts international markets, as trading hours and deadlines may change.
   
   
2. Difference Between DST and Winter Time
   Kindly refer the table 1.1.1.2a for more detailed information.
   
   

   DST (Summer Time)	Clocks are set one hour ahead to extend evening daylight.
   Winter Time	Standard time resumes, and clocks are set back to their original time.

3. Impact on Trading Hours
   Major financial markets in the U.S., Europe, and other regions adjust trading hours based on DST. Kindly refer the table 1.1.1.3a for examples.
   
   

   U.S. Markets	New York Stock Exchange (NYSE) shifts from EDT to EST.
   European Markets	London Stock Exchange (LSE) and other European markets shift between BST and GMT.

4. Considerations for Ticket Resolution
   Refer to table 1.1.1.4a for the considerations.
   
   

   Check Current Time Zones	Confirm the current time zone of the market or region involved in the ticket.
   Adjust for Time Difference	If resolving issues with clients or partners in other time zones, ensure all parties are aware of the correct trading hours.
   Account for Overlaps	During transition weeks, some markets may overlap differently, affecting certain trades and order submissions.

5. Region-Specific Observances
   Refer to table 1.1.1.5a for more details.
   
   

   U.S. and Canada	DST typically ends in November and resumes in March.
   Europe	DST generally ends in October and resumes in March.
   Asia	Most countries, like Japan and China, do not observe DST, maintaining the same time year-round.
   Middle East	Countries like Israel observe DST with adjustments similar to Europe.
