Unless the values are in the format that Org uses to clock time spent on tasks
it will not be able to process it.  In future you can start and stop the clock
with point on the task and pressing C-c C-x C-i and C-c C-x C-o respectively
while in Org file or using I and O while in agenda view.  See
http://orgmode.org/manual/Clocking-work-time.html#Clocking-work-time for
details.

Since you have already worked and noted the times, you will again have to do
some more manual work to get what you want from Org.  You will need to add a
LOGBOOK drawer beneath every task you want to record time for - you can either
copy-paste or can try C-c C-x p to add the drawer.  Then you can add the time
periods like shown below.  A quick way would be to just clock in and out of
task so as to get clock lines there and either manually edit the times or use
magical Shift-up or Shift-down to adjust the clock lines.  You can press C-c
C-y on the clock line in case you manually edit the time to recompute the
totals.

,----
| * A Task
|   :LOGBOOK:
|   CLOCK: [2009-04-07 Tue 02:30]--[2009-04-07 Tue 03:00] =>  0:30
|   CLOCK: [2009-04-07 Tue 01:00]--[2009-04-07 Tue 02:00] =>  1:00
|   :END:
`----

Once you have clocked times like this then you can get the total for the time
spent under CLOCKSUM column in column view or you can get a report in the
agenda file itself with clocktable report (C-c C-x C-r).
