This change makes strftime() go faster and makes it possible to format timestamps through the big bang to most of the stelliferous era. India has also been added as a timezone to most binaries. Since we were able to change the struct tm abi, this makes cosmopolitan libc superior, to just about everything else, when it comes to standing the test of time
