-----------------------------------------

Hey [~maedhroz],

I understand you've worked on this before. But, if it's fine with you, I'd like 
to work on this. I'm a new contributor, and most of the other low hanging fruit 
issues are either taken or seem intimidating.

Thanks!

> CASSANDRA-15241 changed {{Dispatcher}} to use the {{approxTime}} 
> implementation of {{MonotonicClock}} rather than {{nanoTime()}}, but clock 
> drift between the two, can potentially cause queries to time out more 
> quickly. We should be able to revert the {{Dispatcher}} to use {{nanoTime()}} 
> again and similarly change {{QueriesTable} to {{nanoTime()}} as well for 
> consistency.
