signal to kernel headers that time_t is 64-bit
linux/input.h and perhaps others use this macro to determine whether the userspace time_t is 64-bit when potentially defining types in terms of time_t and derived structures. the name __USE_TIME_BITS64 is unfortunate; it really should have been in the __UAPI namespace. but this is what was chosen back in v4.16 when first preparing input.h for time64 userspace, presumably based on expectations about what the glibc-internal features.h macro for time64 would be, and changing it now would just put a new minimum version requirement on kernel headers. the __USE_TIME_BITS64 macro is not intended as a public interface. it is purely an internal contract between libc and Linux uapi headers.
