TZSELECT(8)TZSELECT(8)NAMEtzselect - select a time zone
SYNOPSIStzselect [ -c coord ] [ -n limit ] [ --help ] [ --version ]
DESCRIPTION
The tzselect program asks the user for information about the current
location, and outputs the resulting time zone description to standard
output. The output is suitable as a value for the TZ environment vari‐
able.
All interaction with the user is done via standard input and standard
error.
OPTIONS-c coord
Instead of asking for continent and then country and then city,
ask for selection from time zones whose largest cities are clos‐
est 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 frac‐
tion: 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 digits are treated as
DDMM, DDDMM, DDMMSS, or DDDMMSS representing DD or DDD degrees,
MM minutes, and zero or SS seconds, with any trailing fractions
represent fractional minutes or (if SS is present) seconds. The
decimal point is that of the current locale. For example, in
the (default) C locale, -c +40.689-074.045 specifies 40.689°N,
74.045°W, -c +4041.4-07402.7 specifies 40°41.4′N, 74°2.7′W, and
-c +404121-0740240 specifies 40°41′21″N, 74°2′40″W. If coord is
not one of the documented forms, the resulting behavior is
unspecified.
-n limit
When -c is used, display the closest limit locations (default
10).
Applications should not assume that tzselect's output matches the
user's political preferences.
--helpOutput help information and exit.--versionOutput version information and exit.ENVIRONMENT VARIABLES
AWK Name of a Posix-compliant awk program (default: awk).
TZDIR Name of the directory containing time zone data files (default:
/usr/local/etc/zoneinfo).
FILES
TZDIR/iso3166.tab
Table of ISO 3166 2-letter country codes and country names.
TZDIR/zone.tab
Tables of country codes, latitude and longitude, zone names, and
descriptive comments.
TZDIR/TZ

EXIT STATUS
The exit status is zero if a time zone was successfully obtained from
the user, nonzero otherwise.
