            Hello, I haver a time event (AbsTime) reported as a double and I want to pull out the time since the 1st event (E0)
How can I report out this - thanks
events = 
  1×6 struct array with fields:
    Type
    Data
ans = 
  struct with fields:
          AbsTime: [2025.00 2.00 10.00 20.00 16.00 8.34]
      FrameNumber: 0
    RelativeFrame: 0
     TriggerIndex: 0
ans = 
  struct with fields:
          AbsTime: [2025.00 2.00 10.00 20.00 16.00 11.90]

This is how I actually get it:(and  I Thought (E5-E0) would do it.
          events = vid.EventLog   %Events log from video object
          format bank  
          E0=events(1).Data.AbsTime  
          class(E0)
          E5=events(5).Data.AbsTime  
          E5-E0

        elapsed_as_duration = datetime(E5) - datetime(E0);
Now you can ask things such as
seconds(elasped_as_duration)
