About the date/time stuff. We (of course) had the exact same issues
with dates and times when we did a native port of 7.1.3. Since we want
to represent dates and times with exactness of nanoseconds from
thousands of years BC up to thousands of years in the future, it was a
major piece of work. The code base is not titanically large, but it was
pretty tricky getting it right.
First the bad news:
There is no native data type in the C lanaguage that can store with the
required precision so we used Moshier's Qfloat. With PostgreSQL,
perhaps the intermediate values could be stored in numeric type instead.
Now the worse news:
Everything is in C++ and represented as objects
Maybe it would not be too hard to translate the algorithms into C, since
the languages are fairly similar.
