Okay, that sounds good, I’m glad you got a resolution that works for you.
If you are interested, you can check out my free template that has built in functionality for bookings with timezone and daylight savings aware.
In the video below I demonstrate a booking and how the users current timezone is detected and populated by default, but while selecting their desired timeslot, they can choose to change their timezone and the selected date and available timeslots displays are updated to reflect that newly selected timezone.
In the video I also demonstrate the day light savings aware. In my timezone, Asia/Bangkok, we do not follow daylight savings. In NYC it falls around March 9th this year, so I select March 7 and then March 14 to demonstrate the difference in the America/New_York timezone due to the day light savings change.
