/** \brief ARTIMTimer
* This file contains the code for the ARTIM timer.
*
* Basically, the ARTIM timer will just get the wall time when it's started,
* and then can be queried for the current time, and then can be stopped (ie,
* the start time reset).
*
* Because we're trying to do this without threading, we should be able to 'start' the
* ARTIM timer by this mechanism, and then when waiting for a particular response, tight
* loop that with sleep calls and determinations of when the ARTIM timer has reached its
* peak. As such, this isn't a strict 'timer' in the traditional sense of the word,
* but more of a time keeper.
*
* There can be only one ARTIM timer per connection.
