sdesc: "The time zone package"
ldesc: "The public-domain time zone database contains code and data that represent the history of local time for many
representative locations around the globe. It is updated periodically to reflect changes made by political bodies to UTC
offsets and daylight-saving rules.

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."
