/*
 * Summary:
 *
 * This code tests the behavior of time-related functions in the presence of
 * system clock changes (jumps). It requires root/Administrator privileges in
 * order to run because it changes the system clock. NTP should also be disabled
 * while running this code so that NTP can't change the system clock.
 *
 * Each function to be tested is executed five times. The amount of time the
 * function waits before returning is measured against the amount of time the
 * function was expected to wait. If the difference exceeds a threshold value
 * (defined below) then the test fails.
 *
 * The following values are intentially:
 * - more than 200 milliseconds
 * - more than 200 milliseconds apart
 * - not a multiple of 100 milliseconds
 * - not a multiple of each other
 * - don't sum or diff to a multiple of 100 milliseconds
