-  Calculate difference between two datetime values as seconds + microseconds.

-  SYNOPSIS
-    calc_time_diff()
-      l_time1         - TIME/DATE/DATETIME value
-      l_time2         - TIME/DATE/DATETIME value
-      l_sign          - 1 absolute values are substracted,
-                        -1 absolute values are added.
-      seconds_out     - Out parameter where difference between
-                        l_time1 and l_time2 in seconds is stored.
-      microseconds_out- Out parameter where microsecond part of difference
-                        between l_time1 and l_time2 is stored.
-
-  NOTE
-    This function calculates difference between l_time1 and l_time2 absolute
-    values. So one should set l_sign and correct result if he want to take
-    signs into account (i.e. for TIME values).
-
-  RETURN VALUES
-    Returns sign of difference.
-    1 means negative result
-    0 means positive result
