[tahoe-dev] Minor patch to parse_date to provide additional resolution to expire.cutoff-date

I have setup a private personal (I'm the only one using it) Grid using
three nodes. However I do not have a lot of disk space available, so I
sometimes need to cleanup disk space usage. I have done this by using
the cutoff-date garbage collector. However it only provides date level
resolution. So If in the morning I allocate a lot of space and by
afternoon decide it was a waste. I cannot clean it up until tomorrow.

To alleviate this, I modified parse_date so that it can accept a
complete UTC timestamp. I can then edit tahoe.cfg to have a full UTC
timestamp in the expire.cutoff-date field. I have included a "darcs
send" of the change below (I am new to darcs, so hopefully I did this
correctly!). You are welcome to incorporate this into the official
sources, or not. Thanks.
