In computing, zic stands for the zone information compiler, a component of the IANA tz database. It converts text-based time zone rules into binary data used by standard libraries to apply time zone and daylight-saving rules. Administrators run zic after updating tzdata, typically to install the new zone files into the system's zoneinfo directory.
