Talking about 128bit time formats or so: With today's computing power (just
think of MP3 decoders), a switch to BCD coded time in 128 bit should be
sufficient:
Byte#: 1 2  3  4  5  6  7  8  910 111213 141516
Value:2006-07-18 09:26:13.12 1234 567890 123456

So you'd have significant sub-picosecond resolution and peace until year
"9999".

Ulrich
