-    NAME
-        CsrTimeUtcGet
-
-    DESCRIPTION
-        Get the current system wallclock time, and optionally the current system
-        time in a low and a high part as would have been returned by
-        CsrTimeGet.
-
-        Although CsrTimeUtc is expressed in seconds and milliseconds, the actual
-        resolution is platform dependent, and can be less. It is recommended
-        that the resolution is at least 1 second.
-
-    PARAMETERS
-        tod - Pointer to variable that will receive the current system
-              wallclock time.
-        low - The low part of the current system time in microseconds. Passing
-              NULL is valid.
-        high - The high part of the current system time in microseconds. Passing
-               NULL is valid.
