 *  @file    Time_Service_Test.cpp
 *
 *  This example tests the Time Service server and clerk
 *  components. The test forks and execs two processes to run both
 *  the clerk and the time server. The clerk and the server
 *  communicate for a short duration after which the main process
 *  kills both the processes. No command line arguments are needed
 *  to run the test.
