    tests/timer: Skip test_timeval_to_iso8601_overflow if we can't overflow a GTimeVal
    
    On 32 bit systems, the size of a long might be the same as the size of
    an int. In that case, we won't be able to get an overflow when
    converting from a GTimeVal to a time_t. Skip the test for this in that
    case.
