Not sure what this has got to do with SSIS but its an interesting little puzzle for a Friday afternoon anyway.
Paste the following into SSMS/QA and run it:
declare
@mins int
set
@mins = 130
select
cast(@mins/60 as varchar(5)) + ':' + RIGHT('0' + cast(@mins%60 as varchar(2)), 2)
There are probably other, better, ways!!!
