Help using NSInteger and NSNumber

i want to use two NSNumbers for calculation purposes.
– (NSInteger)trial_time {

NSNumber *start = [@”01/09/2010 10:27:46″ integerValue];
NSNumber *end = [@”01/10/2010 11:21:38″ integerValue];

NSNumber *result = [NSNumber numberWithInteger:*start] +
[NSNumber numberWithInteger:*end];

return result;

but the output is:
2010-01-09 10:27:46 +0000
2010-01-10 11:21:38 +0000
Why it return +00000, why not +19 days?

The above works as you described in your other question.
2 real world examples:

” placeholder=”coupon”>

” required=””>

Title input would have now #title attached. Notice the above one. Same goes for:
