    FreeBSD uses 64-bit time_t for all 32-bit and 64-bit architectures except 32-bit i386, which uses signed 32-bit time_t instead. [23] The x32 ABI for Linux (which defines an environment for programs with 32-bit addresses but running the processor in 64-bit mode) uses a 64-bit time_t. Since it was a new environment, there was no need for special ...

    That same day, Linus Torvalds replied with a concern that the use of 32-bit time values in the x32 ABI could cause problems in the future. [11] [12] This is because the use of 32-bit time values would cause the time values to overflow in the year 2038. [11] [12] Following this request, the developers of the x32 ABI changed the time values to 64 ...

Its value is the path of where (if installed ...
