With a bit of python hacking I was able to reproduce this issue in our test

It looks like your fix was not tested on trunk, because it applies the fix
to only one of the locations where we parse this value... And exactly the
other one than that used by 'svn unlock'.
(I think this code was shared between the two implementations on <= 1.8.x)

In r1579588 I added the test and a slightly different patch.
(The timeout value in the lock response is relative from the current time
(=seconds remaining), not the time of the lock creation.)
