In this case: YAGNI, ignore my comment. Use fractional seconds. :-)

It's really pointless for your average desktop or server CPU. But
most ARM and MIPS CPUs have no hardware FP support. These are
used a lot for embedded devices. But since Intel and AMD have
announced to invade that niche with their x86 designs, the
situation will be quite different in a few years.

Ick, please no. If anyone absolutely needs microsecond precision
timing, then the last thing they need is one object allocation
per query (taking quite a few microseconds ...). :-)

Avoid falling into the BDUF trap.
