…#744) `resource.CopyObject` and `resource.CopyObjectInto` incorrectly zero `time.Time` values when doing their copy, as it tries to copy `time.Time` instances as structs using reflection. Since `time.Time` has no exported fields, this does not work. To fix this behavior, check if the struct to be copied is `typeOf(time.Time)`, and, if so, directly copy it with `dst.Set(src)`, rather than recursively calling `CopyObjectInto` to copy it as a user-defined struct. This does bring up the issue that any other "special" types which have custom `MarshalJSON`/`UnmarshalJSON` implementations but no exported fields will also fail with the deep copy performed by `resource.CopyObject`/`resource.CopyObjectInto`. I'm not sure if this is a restriction we want to live with, or attempt to solve here. Ultimately, a better solution would be to avoid using relfection for copying objects entirely, and rely on generated deep copy methods in objects (see #424).
