FILE LIST - 
             testGmtime.c

DESCRIPTION -
	     This file compares the current local time with GM time.
	     malloc:
	     This routine allocates a block of memory from the free list.
	     The size of the block will be equal to or greater than nBytes.
	     RETURNS a pointer to the allocated block of memory, or a
	     null pointer if there is an error.

	     assert:
	     If an expression is false (that is, equal to zero), the assert()
	     macro writes information about the failed call to standard erro
	     in an implementation-defined format.  It then calls abort().  The
	     diagnostic information includes:

	     -the test of the argument
	     -the name of the source file (value of preprocessor macro __FILE__)
	     -the source line number (value of preprocessor macro __LINE__).
	     RETURNS N/A.

	     tmcmp:
	     This routine compares two structures (member against member).
	     RETURNS a value of false (that is, equal to zero) if the
	     expression are not equal, or returns true otherwise.

	     To run this code invoke the function testGmtime().

RUNNING DEMO -
	     Place the testGmtime.c in your <Tornado> dir. Depending on
	     the target you have, define the CPU in your compile line and use
	     the Makefile in the BSP dir. to compile.

TESTED ON -  Host/Target : Solaris 2.5.1 / mv1604
	     VxWorks     : 5.3.1
