The main issue with it is vendor lockin at least until it becomes part of the standard.

For the most part I would use longs to store any business date information on a database. This gives me the flexibility to adjust the precision as I see fit. In most cases I just convert them to java.util.Date.

Time zones I would treat to be a presentation level issue than a data issue. This simplifies the database and increases portability since databases can represent temporals in different fashions.

The standard Calendar class provides me with some date manipulation functions which I convert to millisecond since epoch data.

As for nanosecond precision I would store that as an offset from 0 as a separate long column.
