Thanks Skip, what i currently i have is: 

   dt = datetime.now()

and 
   self.logfile.write('%s\t'%(str(strftime("%Y-%m-%d", ))))
   self.logfile.write('%s\t'%(str(strftime("%H:%M:%S", )))) 
   self.logfile.write('%s\t'%(str(dt.microsecond))) 

what i get is this:

2013-08-02	09:52:20	312961
2013-08-02	09:52:20	313274

2013-08-02	09:52:20	688740
2013-08-02	09:52:20	688963

is the third column is only the microsecond?  how could i get this to write with the rest of the time (the hh:mm:ss) ?
