How do I get TimeZone name from numeric offset?

[tsquillario]

I'm returning a DateTimeOffset from a my backend like 2023-06-17 18:30:00.0000000 -06:00. I'm trying to figure out how to get the timezone name from the offset -06:00. Is there any way to do this?

I have a DropDown which is a list from tz.timeZoneDatabase.locations and I'd like to set the correct value without storing the timezone name string in my database. Thoughts?

I see why this is not possible, one offset could return multiple timezones. You could lookup the offset in milliseconds but would have no way of knowing which timezone was the correct one. Closing.
