Formatting integers with io_lib

I may have missed or misunderstood something in the io_lib and io
library documentation, but is there a way to use io_lib:format() to
insert leading zero characters on small integers? For example, in the
Erlang shell:
{_,Time} = calendar:local_time().
{H,M,S} = Time.
Msg = io_lib:format("~w:~w:~w", [H,M,S]").
io_format("~s", Msg).
I get "15:2:9". I would like to get back "15:02:09", and of course when
the integer is two digits I would not like the leading zero.
Is there a similar way to do this like with the C stdlib and the %0n
where n=2 formatter?
printf("%02d:%02d:%02d", h, m, t);
I would appreciate any pointers or tips. Thank you!
