Don, nominal_time means the time the report is valid. the algorithm i use is if the report is before 45 minutes after the hour then nominal_time == ob time otherwise nominal_time is set to be the zero minute of the next hour. this is what the documentation states but it's dated 1996 so i don't know if the nominal_time definition has changed in the latest specs.
