I need to store time values for a full day in two separate comboboxes (24 hours in each) for start time and end time selection, 15 minute increments. Is it better to use a value list for these times and set the field value for date/time in the table...or use a value list with an index; time value and store the field value as a number/index for the combobox? I need to be able to retrieve this value for reporting. I'm new and trying to normalize my db
