http://orgmode.org/org.html#Resolving-idle-time
I just discovered this, and it was one of those 'wow, org-mode already
does this' moments.
I really like being able to get distracted from some task, then apply the lapsed
minutes to *more than one* other task. All I have to do is keep running M-x org-resolve-clocks
Thanks!
