What is UTC+00:00?
UTC+00:00 is a fixed numeric difference from Coordinated Universal Time. ISO 8601 notation +00:00 records this difference from UTC.
Fixed UTC offset
Current time at UTC+00:00
UTC+00:00 is a constant clock offset from Coordinated Universal Time (UTC). It does not represent one country or city and never changes for daylight saving time.

Syncing • Using device time Note: the value above does not include device-clock drift accumulated after calibration. This is generally no more than ±1 ms per minute, but the actual rate varies by device. The lowest round-trip latency measured between your browser and the current time-service node. It is typically affected by physical distance, network routing, access quality, and current congestion. Network latency describes the measured connection. It is separate from the estimated time-error range and must not be treated as that range or divided in half. This error does not show whether your device clock is fast or slow.

Fixed UTC offset FAQ
Is UTC+00:00 a time zone?
No. It is a numeric offset. IANA time zones such as Asia/Kolkata contain geographic and daylight-saving rules and can use different offsets on different dates.
Does UTC+00:00 observe daylight saving time?
No. This page keeps the offset constant. A city or IANA zone currently using this offset may later stop using it when entering or leaving daylight saving time, or when the government changes local time rules.
