You can use the ParseTime function to turn a string value into a time. So if there are attributes Start and End, this should work:
TagAvg('Attribute_Name', ParseTime('Start'), ParseTime('End'))
After much experimentation I did finally get working results using the ParseTime() method. In my case this is the syntax that worked:
In this case the start time and end time values are string attributes in a parent element.
