Guide: Time Zone Converter

Adds/subtracts a static offset hours from a datetime string.

Enter time and offset, then convert.

UTC = local − offset (sign convention as labeled).

12:00 with +3 offset → 09:00 UTC if defined that way in the tool.

Why not full time zones?

Real zones use DST and historical changes; this is a simplified offset model.

Sign of offset?

Confirm whether positive offset means east of UTC per the form’s definition.

Flight schedules?

Use airline-published local times and official zone databases for accuracy.
