It seems that everyone is writing timers in this period :) I've my
implementation too, resulting from preliminary off-list discussion
with Pavel Vozenilek. It's similar to yours but I was not happy with
the interface, and also wanted to make it interoperable with
Boost.Date_Time without actually coupling with it.

I appreciate a lot the enormous amount of work you are doing on this
and other proposals (and it seems you are writing code faster than I
can even comment on it :)) but I'm afraid this time we should refrain
from submitting a component for which there's no existing practice. It
can always be included later, even if criteria for inclusion will be
much stricter.
