Timezone Boundary Builder converts OpenStreetMap's coverage of time zones into a shapefile based on boundary=timezone relations and timezone=* tags on boundary=administrative relations. It is the successor to Eric Muller's tz shapefile, which was discontinued in 2016. Timezone Boundary Builder is the principal open data source used with the tz database, a public domain, collaborative database of time zone metadata sponsored by ICANN. The tz database is an industry standard used by most modern operating systems, standard libraries of programming languages, database servers, and firmware.
