Coordinated Universal Time is kept by atomic clocks and adjusted with leap seconds so that it stays close to Earth's rotation. WorldTimeNow treats UTC as the baseline for offsets, conversion, and comparisons. UTC does not change for daylight saving. When a city says it is UTC+05:30, that figure is measured against this scale, not against a local wall clock in England or France.
The offset shown above is computed from UTC at page render time using Intl.DateTimeFormat. It can change when daylight saving starts or ends.
UTC does not observe daylight saving time. The offset remains UTC+00:00 all year.
