CUURENT in Stored Procedure

I use SCO OpenServer 5.x and Informix 7.x My USEOSTIME is set to 1 (Seems if this only enable the fraction part) The date_stamp is declared as DATETIME YEAR TO FRACTION(5) Maybe this question was asked before, but I would like to ask it again. If I use CURRENT at different places in a stored procedure, I get the same values. I would like the Stored Procedure to log in milliseconds the time it takes to execute. I would like to get the time in the beginning and then also at the end of the procedure. I have replaced the CURRENT with another stored procedure that I call that use CURRENT, but no luck. Any help please? Example: CREATE PROCEDURE sp_check_speed() DEFINE l_start_time DATETIME YEAR TO FRACTION(5); DEFINE l_end_time DATETIME YEAR TO FRACTION(5); LET l_start_time = CURRENT; {Do lot of work and selects, take about 3 second} LET l_end_time = CURRENT; {Write the Start and End time into a table, but the time is the same} END PROCEDURE; Regards David
