Cities in the Europe/Dublin zone
The identifier Europe/Dublin comes from the IANA time zone database (tz database) used by operating systems, browsers and programming languages. A zone in this database is an area where clocks have agreed since 1970 – which is why one country can have several zones with the same offset.
