GMT to UTC time conversion
The difference between GMT and UTC is fixed: UTC is the same time as GMT. For example, 9:00 AM (09:00) GMT is 09:00 UTC, and 6:00 PM (18:00) GMT is 18:00 UTC. The chart above lists the conversion for every hour of the day.
These conversions use each zone's standard UTC offset — UTC+00:00 for GMT (Greenwich Mean Time) and UTC+00:00 for UTC (Coordinated Universal Time) — so the result is exact and does not shift with Daylight Saving Time. To convert a real calendar date between cities with automatic DST handling, use the full time zone converter.
