I was thinking on that, but since you need at least 20 bits, so 32,
for microseconds I would suggest nanoseconds, which fit in 32 too.
Sure, nanos seems too much for the current time but it pushes the
future problem further down, nearly forever for comms between
different machines until someone develops FTL networks.
