Printing current time to a file

[zolaris at gmail.com]

I am trying to print the current system time to a file.  I know only a
little bit about Python.  I have gotten the very simple:

Print time.time()

to work properly.  From what I gather the line to print it to a file
should look like:

self.log.write(time.ctime(time.time()))

But that prints nothing in the file assigned to log.  Is there
something I should be doing extra?

Thanks.
