Hadn't seen it.. Weird, though, that the "fix" is so simple and wasn't implemented by default. Oh well..

Anyway, probably more important than displaying end time for a call is the duration of said call (preferably in human-readable form.. 1:20 as opposed to 80seconds). Of course, if we could have all of it, start;end;duration, even better.

The talk says adding those triggers is relatively safe.. There doesn't seem to be any system-default triggers and running that batch command resets the list so unless some other app decides to overwrite them, it should be relatively safe putting that into your app's pre- or post-installation scripts.
