You didn't read (or at least you did not quote) the second part of my
suggestion which was that "micro" perhaps ought to be viewed as meaning
"small", i.e., "subsecond" in the context of time.  So it's nanoseconds,
now.  If we go orders of magnitude smaller, what then?  picotime() replaces
microtime()?  I mean, granted, we're going to hit lim(C) pretty quick unless
we have some SERIOUS scientific breakthroughs, so it's not likely to go past
picotime(), if we get that far!, but must we keep renaming things every
time we jump to a smaller/larger unit of measurement?  This seems
ludicrous.

see above.  I think "micro" is, in this case, taken too literally (in the
context specific to time as 'microseconds') or not literally enough (in
the general context of "very small").
