When retrieving the last modification time of a file on the server via the
method getModificationTime(String filename) it returns something like
"213 20141111112706" where only the part after the space is the relevant data.
I digged deeper and i found that the first part before the space is the positive
response code which is not removed before getModificationTime returns.
I consider this a minor bug as i think there is a simple work around
(split by space, use second part only) but i do not believe that
the result of the method is what a user expects regarding the documentation
of that method.
