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
