Int32x32To64 macro internally truncates the arguments to int32, while time_t is 64-bit on most/all modern platforms. Therefore, usage of this macro creates a Year 2038 bug.

I detailed this issue a while ago in a writeup, and spotted the same issue in this repository when updating the list of affected repositories:
