 * Verify estimated host time from nanoapp.

 * Fundamentally, there are two phases to this test:
 *   1) Verify that time does increase at some point
 *   2) Help verify that AP time is "close" to what nanoapp can get.
 *      Timestamps are sent to the host when a message is received by
 *      the test. The host then passes or fails the test depending on
 *      how close the timestamps are after accounting for the round
 *      trip time.
