One obvious point is that you should determine what operations are needed
that are not provided by the standard. Remember that Ada 2005 includes
additional date/time operations for time zones, arithmetic, and formatting,
so it doesn't make much sense to re-invent the wheel in those areas. It also
expands the range of years upwards.
What's missing there (more advanced time zones, fancy date and time output)
probably can be built on top of those packages better and quicker than
starting from scratch.
Randy.
