Thanks for the explanation.

I just found out where my problem lies. The svn_time_to_cstring delivers
the correct GMT date but mailer.py then prints the date in the human
readable form. As a result of this the output of mailer.py depends on the
time zone of the caller and therefor I will always get differences
between my output and the expected one which is found in mailer-t1.current.

So I think the only possibility to avoid this is to set the local timezone
to GMT before running the test (or setting it within the test). Or do you
have any other idea?
