- Subject: [PATCH v6 0/2] Y2038 support - __time64_t and __tz_convert
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.
