And not only they get faster, they also get more parallel. If you have say 36 cores in the server, who guarantees that they don't ask for time at exactly same nanosecond?

I was always taught to NEVER use TIME as a key. Even if your system
works now what happens if you upgrade the hardware and it is so much
faster that two rows can be inserted with in the granularity of the
systems timer?
