Variable: zoneinfo-style-world-list
zoneinfo-style-world-list is a customizable variable defined in
time.el.gz.
Value
(("America/Los_Angeles" "Seattle") ("America/New_York" "New York")
("Europe/London" "London") ("Europe/Paris" "Paris")
("Asia/Kolkata" "Delhi") ("Asia/Tokyo" "Tokyo"))
Documentation
Alist of zoneinfo-style time zones and places for world-clock.
Each element has the form (TIMEZONE LABEL). TIMEZONE should be a string of the form AREA/LOCATION, where AREA is the name of a region -- a continent or ocean, and LOCATION is the name of a specific location, e.g., a city, within that region. LABEL is a string to display as the label of that TIMEZONE's time.
This option has effect only on systems that support TZDB-style
TZ strings specified as AREA/LOCATION. In particular,
MS-Windows doesn't support that; use legacy-style-world-list instead.
Also, AREA/LOCATION must specify a timezone supported by your system,
otherwise the behavior depends on the underlying OS and library.
This variable was added, or its default value changed, in Emacs 23.1.
