-# tzdb_to_nx
-
-This is a CMake/C++ project to convert RFC 8536 time zone data to the Nintendo Switch's format.
-This makes use a lot of Unix system calls as well as a bash script to convert the data, so it likely requires a bit of work to port to a non-POSIX platform, such as Windows.
-
-Intended for use with the [yuzu Emulator](https://yuzu-emu.org/) project, but the project in the future likely won't ship synthesized Switch archives.
-That leaves this project in a place where it is not likely to be used, but will remain here as a reference.
-
-- tzdb: CMake and bash script to build and convert time zone data from https://www.iana.org/time-zones into the Nintendo Switch's format.
-- tzdb2nx: C++ program that converts a single tzif file to the Nintendo's format.
-
-The fine folks over at [SwitchBrew](https://switchbrew.org/wiki/PSC_services#ITimeZoneService) have left very helpful information on reading the data.
-Nintendo's file is simply the TZif version 2 data, with standard_indicators and ut_indicators data stripped out (and the necessary modifications needed in the header to make the data valid).
-This means the TZif 1 data is not present, so essentially we are left with the second half of each file.
-
-Nintendo also does not seem to run the `zic` program on their output when they build the time zone data.
-I have left the relevant build command for that in src/tzdb/CMakeLists.txt commented out, but it isn't used here.
-This lets the project produce data identical to Nintendo's firmware for time zones, however this code does not produce the time zone data on US/Pacific-New or America/East-Saskatchewan (I may have bunged up the actual paths for these as this is 3 day old memory).
-
-The CMake and C++ code in this repository is licensed under the MIT License.
-The source files date.c, newstrftime.3 and strftime.c from submodule eggert/tz use the BSD-3 clause license [[source]](https://github.com/eggert/tz/blob/main/LICENSE).
-The time zone data output from this repository, like those found in archives in the Release setcion, is in the public domain [[source]](https://github.com/eggert/tz/blob/main/LICENSE).
