The first patch introduces __TIMESIZE (which is the bit size of time_t at glibc build time, and equals __WORDSIZE except for x32 where __WORDSIZE is 32 but __TIMESIZE is 64) and __time64_t, the 64-bit counterpart of time_t, to be used in 64-bit-time implementations of public APIs related to time. Note that __time64_t replaces internal_time_t previously introduced. The second patch makes __tz_convert compatible with 64-bit time. This implies creating 64-bit-time versions of its callers and turning their original versions into wrappers if they were 32-bit-time. These patches are functionally tested as part of the whole Y2038 patch series using the ad hoc framework at https://github.com/3adev/y2038 which runs tests using times below, at and beyond the Y2038 limit. These patches were also run through build-many-glibcs.py to ensure that existing glibc configurations are not broken. The minimal configuration set is x86_64-linux-gnu, aarch64-linux-gnu, powerpc-linux-gnu, and arm-linux-gnueabi.
