Well, how is the interpreter supposed to know that they are times?
Remember that the Python language doesn't have times as a basic data
type, and input(...) treats what you enter as Python data (unlike
raw_input()).

Well, the code I posted was untested, and I find two things wrong with
it straight away: Firstly, it won't include leading zeros when
converting seconds to a time, and secondly it puts the hours, minutes
and seconds in the wrong order.

The idea, though, is to read strings lime "07:20:44" and convert them
into something that Python *can* do arithmetic on. I defined a function,
timetosecs, that would let you do this.
So your program should look something like:
# Put function definitions here ...
CT = raw_input("input your chronometer time (ex. 07:21:46): ")
CE = raw_input("input your chronometer correction (ex. 00:01:32): ")
CEfastslow = raw_input("is your chronometer correction fast or slow: ")
Tsecs = timetosecs(CT)
Esecs = timetosecs(CE)
#decide either to subtract or add CE from/to CT
if CEfastslow == "fast":
CEfastslow = Tsecs - Esecs
if CEfastslow == "slow":
CEfastslow = Tsecs + Esecs
print "New time:", secstotime(CEfastslow)
Hope this gets you a bit closer to a solution.
