ID string in zic's output files
by Arthur David Olson Feb. 22, 2017

Feb. 22, 2017

So much for the idea of storing ID strings in zic output files as (unused) abbreviations. The zone America/Pangnirtung needs 41 bytes to store all the abbreviations it uses: -00 AWT APT AST ADDT ADT EDT EST CST CDT A zic output file can have at most 50 bytes of abbreviations, as set by TZ_MAX_CHARS in tzfile.h The 9 bytes remaining isn't enough for our purposes. (We don't want to boost TZ_MAX_CHARS; localtime.c checks files to ensure they have at most that many abbreviation characters; files with more would be rejected, at least by now-in-the-field binaries compiled from localtime.c) Note that the last component of "Zone" names (such as the "Vevay" in "America/Indiana/Vevay") would fit in the 15 "reserved for future use" bytes at the front of zic output files; full names would not (always) fit, and there would not (always) be room for a prefix such as "@(#)." @dashdashado
