// $Id$
// ============================================================================
//
// = LIBRARY
// tests
//
// = FILENAME
// Time_Value_Test.cpp
//
// = DESCRIPTION
// This is a simple test of ACE_Time_Value. No command line arguments
// are needed to run the test. It also tests the ACE_U_LongLong class.
// Because ACE_U_LongLong is used for ACE_hrtime_t on some platforms,
// this seems like a reasonable place to test it.
//
// = AUTHOR
// Prashant Jain <pjain@cs.wustl.edu> and David Levine <levine@cs.wustl.edu>
//
// ============================================================================
// Note, for this test the config.h file *must* come first!
