Hi @MatthewSteger,

Thank you for posting in Intel community forum, hope all is well and apologies for the delayed in response.
Per my understanding the time_t function is a arithmetic type from C++ and it depends on the systems it is used, it can be 32-bit or 64-bit.
Hence would recommend to use use the _time64 to solve the Jan 18'2038 issues. (more details can be refer here)

As for the quartus version that are supporting 64-bit, after some investigation would recommend to try on the Quartus 19.2 pro version and above that comes with gcc 8.3.1 above, which should support the64-bit build.
Hope that clarify your doubts.

Best Wishes
BB
