outputting time in microseconds or milliseconds

[matt.doolittle33 at gmail.com]

Hey everybody,

I am using 2.7 on Ubuntu 12.10.  All I need to do is to print time with the microseconds.  I have been looking at the docs and trying things for about half a day now with no success.  Currently my code looks like this:

        #  write date and time and microseocnds
        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(time())))

the output looks like this:

2013-08-02	06:01:43       00:00:00	
2013-08-02	06:01:43       00:00:00					
2013-08-02	06:01:43       00:00:00				
2013-08-02	06:01:43       00:00:00						
2013-08-02	06:01:43       00:00:00						
2013-08-02	06:01:43       00:00:00				
2013-08-02	06:01:43       00:00:00						
2013-08-02	06:01:43       00:00:00						
2013-08-02	06:01:43       00:00:00						
2013-08-02	06:01:44       00:00:00					
2013-08-02	06:01:44       00:00:00				

as you can see in the 2nd column the observations occur with 'fractional second' frequency, up to 8 or 9 per second.  You can also see my latest attempt to get the microseconds in the third column is not working.  It would really be great if python had a way to just tack the microseconds (actually i think milliseconds would be better) on to the second (in the 2nd column) as a fraction. If this is not possible I need the extra write statement for just the microseconds (millisecond if possible). 

Any help will be much appreciated.
Thanks!
