 It should be possible to just build a time duration for given number of
 seconds for double or float parameters.  Current best way suggested on IRC
 is 'milliseconds (1000 * num_seconds)', but it feels like doing extra
 unneeded work.  Besides, this way I need to choose between
 milli/micro/nano weighing precision loss vs. potential overflow on 32-bit
 machines.  Boost, knowing how many ticks are in a second, could do this
 better.

 What I'm actually trying to do is to call timed_wait() on a condition.
 Currently, I have to

     condition.timed_wait (lock, milliseconds (1000 * num_seconds));

 where as if double was implicitly convertible to time duration I could
 just

     condition.timed_wait (lock, num_seconds);

 which is cleaner and more explicit.
