title: Using on-send add-ins, is it possible to differentiate when a user selects "send" & "send later" within the ItemSend event handler?

  <p>I'm wondering if it's possible to extract timestamp info or any other info indicating if a user pressed &quot;send&quot; or &quot;send later&quot; for a composed message item?</p>
