Eliminate day of week from date and time field

When I push Tech Hours Report to CSV file, the day of week is included in the “Start Time” field. In order to sort by the field I need to manually remove all of the day of week entries from that column. I can easily generate a column with day of week in Excel from the date & time. Please remove the day of week from the “Start Time” in Tech Hours Report. If not in the screen view of the information then in the CSV file that is generated.
