Understanding the GMT to UTC Time Difference
The standard difference between GMT and UTC is 0 hours. GMT and UTC show the same time but are technically different concepts. GMT is a time zone (used by the UK in winter, and several West African countries year-round), while UTC is a time standard maintained by atomic clocks. The distinction matters in computing and science: UTC is the standard reference, while GMT is a timezone that happens to have a zero offset. In everyday use, they are interchangeable, but software should use UTC (or IANA identifiers) rather than GMT to avoid ambiguity.
Best Meeting Times: GMT and UTC Overlap
Since GMT and UTC are identical in practice, there is no conversion needed for scheduling. The important note is that during British Summer Time (late March to late October), the UK shifts to BST (UTC+1) — at that point, UK local time is no longer the same as UTC.
