Date and time begin/end

Time control records are evaluated in order by priority number for the selected term. Because the criteria in the first record that matches by date and time will be applied, time control records must be constructed from the most specific to the least specific. Blank date and hours fields are considered to be wildcards. For example, if the record for Priority Number 1 for term 200010 has no start and end dates, and the record for Priority Number 2 has the date range March 1, 1999 through September 15, 1999, a student attempting add/drop activity on September 1, 1999, would be controlled by Record Number 1. Record number 2 would not be used even though it contains more specific criteria.
