Thanks everyone for your help, I got it all under control. I just got
rid of my " and used /l and that seemed to work just right. And the
issue with the time was that I needed to declare the current date as
cur_date = time.strftime('%m/%d/%Y %H\:%M\:%S', time.localtime()) and
now everything is working fine, but thank you all for offering you
suggestions I really appreciated it!
