I don't. Note that in Nicola's example, which I have verified on my
own machine, the `isdst` field was forcibly overridden: it was
explicitly set to false, but the call to os.time ignored that and
changed it to true anyway. This is most definitely unwanted behavior.
If a user sets a field to a particular value, it should be respected
and not ignored, and most certainly NOT overwritten without notice.

If we do keep this behavior, it needs to be modified to never alter a
field already present, only filling in nil fields instead.
