datetime field

Hi, I've tried running the following procedure : create procedure abc () define starttime datetime year to second; define endtime datetime year to second; define recordproc integer; let starttime=current; let recordproc=30; --call some stored procedures (it takes more than15 mins) let endtime=current; insert into recon_time (start_time, end_time, record_processed) values (starttime,endtime,recordproc); end procedure; When I view from the recon_time table, the start_time and end_time are the same. Does anyone know why ?? Regards Joshua
