Fix printf if time_t is long long

On some platforms, time_t has recently switched from "long" to "long
long" [1]. For these platforms it is necessary to use "%lld" as printf
format specifier because the ABI differs between "long" and "long long".

I found no way for creating something similar to PRId64 for time_t. No
idea how to determine whether it's "long" or "long long". So I cast
everything to "long long" instead.
