    The tz database

    The public-domain time zone database contains code and data that represent the history of local time for many representative locations around the globe.

    +Each location in the database represents a national region where all +clocks keeping local time have agreed since 1970. +Locations are identified by continent or ocean and then by the name of +the location, which is typically the largest city within the region. +For example, America/New_York +represents most of the US eastern time zone; +America/Indianapolis represents most of Indiana, which +uses eastern time without daylight saving time (DST); +America/Detroit represents most of Michigan, which uses +eastern time but with different DST rules in 1975; +and other entries represent smaller regions like Starke County, +Kentucky, which switched from central to eastern time in 1991. +To use the database, set the TZ environment variable to +the location's full name, e.g., TZ="America/New_York".
