27  * Verify estimated host time from nanoapp.
28  *
29  * Fundamentally, there are two phases to this test:
30  *   1) Verify that time does increase at some point
31  *   2) Help verify that AP time is "close" to what nanoapp can get.
32  *      Timestamps are sent to the host when a message is received by
33  *      the test. The host then passes or fails the test depending on
34  *      how close the timestamps are after accounting for the round
35  *      trip time.
