This tool generates the tzlookup.xml file from the countryzones.txt (proto
|
|
text) file. tzlookup.xml is used to associate zones with regions/countries. The
|
|
tool uses ICU4J and IANA data to synthesize some time zone metadata.
|
|
|
|
Besides tzlookup.xml, the tool also generates a tzids.prototxt file
|
|
containing information about zone IDs, id links and "functionally identical"
|
|
zones[1] within each known country. These can be used to map time zone IDs to
|
|
Android's preferred set. This duplicates information from the tzlookup.xml, but
|
|
it is easier to use from host tools than Android's tzlookup.xml's format.
|
|
|
|
[1] i.e. zones that differed in the past but were "folded in" to other zones
|
|
and are not distinct for future times according to IANA or ICU/CLDR.
