(And you can't build a parser for time formats with sub-second time based on the decoded time structure, which is a pain.) I guess the best way to fix this would be to add the micro- and picoseconds as (optional) fields at the end of the decoded time list? It's not very elegant, but it'd be backwards compatible. A different approach would be to make the seconds field something else than an integer, but that would introduce more potential problems, I think...
