tzselect(8) System Manager's Manual tzselect(8)
tzselect - select a timezone
tzselect [ -c coord ] [ -n limit ] [ --help ] [ --version ]
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.
-c coord
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 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 degrees N, 74.045
degrees W, -c +4041.4-07402.7 specifies 40 degrees 41.4
minutes N, 74 degrees 2.7 minutes W, and
-c +404121-0740240 specifies 40 degrees 41 minutes 21
seconds N, 74 degrees 2 minutes 40 seconds 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).
--help Output help information and exit.
--version
Output version information and exit.
AWK Name of a POSIX-compliant awk program (default: awk).
TZDIR Name of the directory containing timezone data files
(default: /usr/share/zoneinfo).
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.
The exit status is zero if a timezone was successfully obtained
from the user, nonzero otherwise.
newctime(3), tzfile(5), zdump(8), zic(8)
Applications should not assume that tzselect's output matches the
user's political preferences.
