Even for a 32-bit build, MSVC expects 'time_t' to be 64-bit - whereas Glib (i.e. GStatBuf) seems to be using a 32-bit version. Since we're passing by address, this will cause problems in a Windows build.
We can kludge this by making sure we pass the expected type for 'time_t'. Ultimately though, it'd be safer to adapt 'localtime_r()' to accept its first parameter by value, rather than expecting a pointer.
