What is UTC?
UTC (Coordinated Universal Time) is the global reference time. Time zones are written as offsets from it — New York is UTC−5 in winter, India is UTC+5:30. UTC itself never changes for daylight saving, which is why servers, aviation (as “Zulu”), and logs use it.
UTC vs GMT: for everyday purposes they show the same time. GMT is also the UK's winter time zone, while UTC is the precise atomic-clock standard.

Frequently asked questions
Does UTC change for daylight saving time?
No. UTC is the same all year. Local offsets change instead — for example London moves from UTC+0 to UTC+1 in summer.
Is UTC the same as GMT?
On the clock, yes — both are UTC+0. GMT is also the UK's winter time zone name, while UTC is the scientific time standard.
What is Zulu time?
Zulu time is UTC. The letter Z marks the zero offset, so 14:30 UTC is written 1430Z.
