Time Difference Averaging

Is there a formula to calculate the average time difference between cells with date & time stamps?

Example: If I have the below timestamps in 4 cells, there would be time differences of 106s, 53s, & 387s. The average of those time differences then would be (106+53+387)/3 = 182s.
