careful with the latest master and your 'real' dives

Hmm. The time conversion functions themselves were actually tested
with millions (literally) of random dates between 1970 and 2099.

But the testing I did was just verifying that the new utc_mkdate()
followed by the (old, and thus tested) utc_mktime() got back the same
64-bit timestamp.

My test program didn't actually test any of the *users* of utc_mkdate().

I can reproduce it by just loading a non-trip dive list, asking for
auto-trip (which makes it all *show* correctly), and then saving the
result.

The trip data save is bogus, even if the dates showed correctly in the
divelist before the saving.
