UTC1

UTC1 is a term that can refer to several different concepts depending on context. The most common interpretation is as a shorthand for the time offset UTC+01:00, i.e., one hour ahead of Coordinated Universal Time. This offset is used by multiple regions, including Central European Time in standard time and West Africa Time, and it is distinct from daylight saving time when the offset can change to UTC+02:00 in summer.

In technical and data contexts, UTC1 may be employed as an identifier, model number, or version code within products, software, or standards. Because there is no universally adopted definition for UTC1 beyond the time offset, its precise meaning is determined by the document or system using it.

As a result, UTC1 is best understood by examining the surrounding text or metadata to determine which sense is intended.
