System Limitations Removed

The 64-bit system interfaces are inherently more capable than some of their 32-bit equivalents. Application programmers concerned about year 2038 problems (when 32-bit time_t runs out of time) can use the 64-bit time_t. While 2038 seems like a long way off, applications that do computations concerning future events, such as mortgages, might require the expanded time capability.
