I don't think this is good enough. If a server stay up longer than 397 days, we could get overlaps.

What you could do, is instead of taking the full time value down to the milliseconds, ignore the rightmost 9 or 10 bits, so the time is only precise to the nearest second or so.

There is more possibility of the counter wrapping then, but it means the server can stay up many years without overlaps.

Also why 20 ms? and the <0 loop looks suspicious to me
