tzselect [ -c coord ] [ -n limit ] [ --help ] [ --version ]

Options

-ccoord

Instead of asking for continent and then country and then city, ask for selection from time zones whose largest cities are closest to the location with geographical coordinates coord. Use ISO 6709 notation for coord, that is, a latitude immediately followed by a longitude. The latitude and longitude should be signed integers followed by an optional decimal point and fraction: positive numbers represent north and east, negative south and west. Latitudes with two and longitudes with three integer digits are treated as degrees; latitudes with four or six and longitudes with five or seven integer

-nlimit

When -c is used, display the closest limit locations (default 10).

--help

Output help information and exit.

--version

Output version information and exit.

DESCRIPTION

The tzselect program asks the user for information about the current location, and outputs the resulting timezone to standard output. The output is suitable as a value for the TZ environment variable.

All interaction with the user is done via standard input and standard error.

ENVIRONMENT VARIABLES

AWK: Name of a POSIX-compliant awk program (default: awk).
TZDIR: Name of the directory containing timezone data files (default: /usr/share/zoneinfo).

FILES

TZDIR/iso3166.tab: Table of ISO 3166 2-letter country codes and country names.
TZDIR/zone1970.tab: Table of country codes, latitude and longitude, timezones, and descriptive comments.
TZDIR/TZ: Timezone data file for timezone TZ.

EXIT STATUS

The exit status is zero if a timezone was successfully obtained from the user, nonzero otherwise.

NOTES

Applications should not assume that tzselect's output matches the user's political preferences.
