what i have so far is :

# Get values needed to make time calculations

CT = input("input your chronometer time (ex. 07:21:46): ")

CE = input("input your chronometer correction (ex. 00:01:32): ")

CEfastslow = raw_input("is your chronometer correction fast or

slow: ")

#decide either to subtract or add CE from/to CT

if CEfastslow == "fast":

CEfastslow = CT - CE

if CEfastslow == "slow":

CEfastslow = CT + CE

but this just doesnt deal with the numbers in time format its acting

like they are just regualr integers adding them up like regular numbers

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()).

i am trying to figure out what u posted and it seems a little

complicated im trying to add it in somehow and figure out exactly what

its doing but still looking for a little easier of a way

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.

thanks so far

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.

Steve
