Yes. The tool automatically determines daylight saving time from the selected date and each city's time zone, so it reflects seasonal changes in the time difference.
If the time-zone difference crosses midnight, the result appears on the previous or next day. Check both the converted local date and time on the Time Difference tab.
The cities and time display settings selected in Quick View are saved in your current browser and persist on your next visit. Clearing browser data may reset them.
