Actually, I've been thinking the same thing. When I wrote the patch adding a new
property looked like the easiest way to get what I wanted, but it's somewhat
limited. It would be useful to be able to use a property for the creation time
of an entry, rather than putting an inactive timestamp in the entry. There's
also the problem of being dependent on the order of the contents of the entry
(the TIMESTAMP and TIMESTAMP_IA special properties return the first timestamp in
the entry), so it only does the right thing if the LOGBOOK and PROPERTIES
drawers are at the top of the entry and in that order.

Having a column view operator for calculating time since would avoid this
problem and be much more flexible. I've been looking at the changes Mikael
Fornius' patch to org-columnview added, and I think I can add a new operator for
this fairly easily.

I still might want to add another special property, for the latest clocked time
for an entry. That way I can have a column for the creation time (stored in a
property) and a column for the last time I worked on the entry.
