extracting single charachters

Hello!

brand new to unix (let alone scripting) I have come hit a step I can't seem to get around.

in a text file I have information such as :-

INFORM_USERS_IB COMPLETED llprod 20011003:100608

What I need to do is extract the 55th and 56t charachter, then insert a : then extract the 57th and 58th.. to give me an end result of:-
10:06

problem is how do I count of extract these charachters as they change frequently but *should* stay in the correct position??
(also does tab count as a single char?)

Or is there an easier way to reformat a date and time string?

Cheers,
James
