You cannot use 32-bit time_t (_USE_32BIT_TIME_T) with _WIN64

I want to migrate from 32 bit to 64 bit and get the error from the title. I am working on visual studio 2012 and I do not know how to solve this.

I would guess that you should better upgrade to visual studio 2019. Maybe 2012 doesn't support 64 bit version properly.

The error is saying that _USE_32BIT_TIME_T is defined (but why?) somewhere in your code or compiler settings. Try to find where it is and remove it.
