Unless you enter your clocked time as a property, org columns will not
be able to do anything with it.

Your best bet, however, would be to use org-mode's excellent clocking
functionality (see description below).

What you have done above is scheduled the tasks to occupy certain time
intervals in your agenda/planner. E.g., Task 1 is scheduled on March 11
from 19:55 to 21:45.

This is *not* the same thing as clocking time spent working on an item.
As far as I know, org-mode cannot calculate time totals based on the
SCHEDULED timestamps.

To log items you will need to clock in on a headling using C-c C-x C-i
and clock out using C-c C-x C-o. Org mode will then create a clock line
listing starting time, ending time, and total time spent.

See this section of the manual for more information:


>> Anyhow, you can set org-columns-default-format, e.g.:
>> --8<---------------cut here---------------start------------->8---
>> (setq org-columns-default-format "%TODO %60ITEM(Task)
>> %5Effort(Estim){:} %5CLOCKSUM(Clock)")
>> --8<---------------cut here---------------end--------------->8---

The clocksum in Manish's example will add the the total time logged via
the method I have described above. 

Estimated effort is a special property that you would need to enter
yourself for each item. (But it sounds as if you are not really
interested in that.)

Hope this helps.
