// although base::Time can represent times from before the Windows epoch and
// after the 32-bit time_t maximum, the conversion between base::Time and
// der::GeneralizedTime goes through the time representation of the underlying
// platform, which might not be able to handle the full GeneralizedTime date
// range. Out-of-range times should not be converted to der::GeneralizedTime. In
// tests, possibly-out-of-range test times are specified as a
// base::Time::Exploded, and then converted to a base::Time. If the conversion
// fails, this signals the underlying platform cannot handle the time, and the
// test aborts early. If the underlying platform can represent the time, then
// the conversion is successful, and the encoded GeneralizedTime can should
// match the test time.
