There it is - stop_time is a str at this point in the program, so has no
strftime attribute or method.  Step back through your code and see why...  I
find Control-F very helpful in situations like this!

There's nothing sacred about the ".ini" extension - any text file that
contains "variable = value" pairs is game.  ConfigObj is not
Windows-centric.  The advantage - which is what I was trying to show when I
posted that gosh-awful hunk of code - is that you can define the format of
the file in one central section of your program - it could even be a
separate module if you wanted - and in one swell foop you tell ConfigObj the
name of the variable, its type, acceptable values or range, and a default
value in case it's missing.  Opening, reading, closing, writing, validating
- all handled.

I certainly wouldn't want to dissuade you from writing your own as a
learning exercise - I'm glad I did - but each time I need to update one of
my old programs that still uses my homegrown ConfigFile, that's the first
thing I re-factor.
