Subtract two timestamps in one event

Hopefully this is a simple question, but I haven't found a way to do so using either the convert or eval commands. Basically, I have two timestamps in my events, a start time and an end time. I want to compute a duration (preferably in seconds) by subtracting the two. Is there a simple way to do this?

Add something like this:

| eval TotalTime = strptime(end_time, "%Y-%m-%dT%H:%M:%S%z") - strptime(start_time, "%Y-%m-%dT%H:%M:%S%z")

(Assuming your date format is in that type of time stamp).

You can use either convert mktime() or the eval strptime() functions to convert both timestamps to epoch time, then just subtract one from the other.
