What is the difference between UTC and GMT?

For everyday use they are the same: UTC (Coordinated Universal Time) is the modern time standard and GMT is the time zone of London in winter. Time zones are written as an offset from UTC, for example UTC+01:00 for Central European Time.

Does the converter handle daylight saving time?

Yes. The offsets come from the time zone database in your browser, so summer or winter time is applied for the selected date – for example, London is UTC+00:00 in winter and UTC+01:00 in summer.
