    I think this is wrong. The ratio should be something like ``<5,1000>`` not 
``<1, 5000>``.

> Since the various time units {{ink_time_t}}, {{time_t}}, {{ink_hrtime}} are 
> all typedefs of C integral types, it is very hard to ensure that units are 
> being converted and compared correctly.
> Consider wrapping these in trivial classes as part of making the time APIs 
> more straightforward. Alternatively, if we move to {{C++11}} investigate 
> {{std::chrono}} for this.
