Hi I have two line in my test log file, which are starting and ending time of my test as: Test Run By asoleyma on Tue Sep 24 12:33:47 2002 runtest completed at Tue Sep 24 12:33:48 2002 How can I calculate the time, in seconds, which my test was running? Note that I know how to use start = time.clock(), but I cannot use it and the only way to have time is getting from log file. Thanks, -Ali
