I would like to include a variable in my email notifications that states how long a node had been down. I'd like the application to take the Reset time (down to the second) and evaluate against the original Trigger Time (down to the second). As I receive UP notification, I would very much like to include some text that reads, "Device was down for 'x' hours, 'y' minutes, 'z' seconds." - but want to possess flexibility to either break out the 'x', 'y', 'z' values or simply have a combined "xx:yy:zz" value. Sure, you could manually review the DOWN alert and the UP alert and do the math in your head, but it would be very nice to have this calculated automatically.
As many different format options there are for denoting time values in an alert, I'd like to see equally flexible options for the "down duration" feature.
