Thanks however I am still having a problem using the time module for arithmetic
My string times are of values such as 09:55:17 and I have code such as: >from time import * >startPoint = strptime(step.sTime, "%H:%S:%M") >finishPoint = strptime(step.fTime, "%H:%S:%M") >duration = mktime(startPoint) - mktime(finishPoint) but it generates the error >OverflowError: mktime argument out of range Cheers -- http://mail.python.org/mailman/listinfo/python-list
