How the UTC to GMT time difference works
GMT is the same time as UTC. Coordinated Universal Time (UTC) is the global time standard the world sets its clocks by.
Greenwich Mean Time (GMT) is the fixed UTC+0 reference time, used by the United Kingdom and Ireland in winter.
For example, 9:00 AM UTC is 9:00 AM GMT.

UTC to GMT questions
Is GMT ahead of or behind UTC?
GMT is the same time as UTC. So 9:00 AM UTC is 9:00 AM GMT, and 5:00 PM UTC is 5:00 PM GMT.
What time is it in GMT when it is 12:00 PM UTC?
When it is 12:00 PM (noon) UTC in Coordinated Universal Time, it is 12:00 PM GMT in Greenwich Mean Time.
How many hours difference is there between UTC and GMT?
UTC and GMT are in the same time zone, so there is no time difference.
Do UTC and GMT observe daylight saving time?
Neither Coordinated Universal Time nor Greenwich Mean Time shifts its clocks for daylight saving time, and they share the same offset, so they stay in sync all year. The United Kingdom and Ireland use GMT only in winter; from late March to late October they switch to British Summer Time (BST), one hour ahead of GMT.
What is the best time to schedule a meeting between UTC and GMT?
A standard 9-to-5 workday overlaps from 9:00 AM to 5:00 PM UTC (9:00 AM to 5:00 PM GMT). Scheduling inside that window keeps the call during business hours in both Coordinated Universal Time and Greenwich Mean Time.
Which cities use UTC and GMT?
Coordinated Universal Time (UTC) covers cities such as Reykjavik, Accra, Dakar, Abidjan, Bamako. Greenwich Mean Time (GMT) covers cities such as London, Dublin, Lisbon, Edinburgh, Manchester.
