Changes

Use C99 (u)int64_t instead of MSVC __int64 extension
 (commit: 501875b)

Use time_t instead of MSVC __time64_t

The documentation reads:

> `time` is a wrapper for `_time64` and `time_t` is, by default,
> equivalent to `__time64_t`. If you need to force the compiler to
> interpret `time_t` as the old 32-bit `time_t`, you can define
> `_USE_32BIT_TIME_T`.
