GMT time-zone questions
What does GMT mean?
On this page GMT can refer to Greenwich Mean Time. The intended meaning depends on the region and date.
Is GMT a unique time zone?
This directory lists one primary meaning, but an IANA identifier is still safer for date conversion.
Can the UTC offset for GMT change?
A fixed abbreviation entry has a fixed offset, but a geographic regional time zone can switch abbreviations or offsets under daylight-saving rules.
What should I enter in the time converter?
Use a city or an IANA time-zone identifier when an abbreviation is ambiguous. This avoids silently choosing the wrong region.
