title: Avg on datetime in Access
body: <p>I am porting some queries from Access to T-SQL and those who wrote the queries used the Avg aggregate function on datetime columns.  This is not supported in T-SQL and I can understand why - it doesn't make sense.  What is getting averaged?</p>
  
  <p>So I was about to start reverse engineering what Access does when it aggregates datetime using Avg, but thought I would throw the question out here first.</p>
