Brian,

Hello.  My patch to get WMS-T support with TileCache requires updates to
a lot of the files in TileCache.  Just using the patched Layers/WMS.py
won't work.  A new version of the patch is below.  Also shown is an
example of applying the patch, relevant to Linux.

http://ak.aoos.org/data/patch/tilecache_aoos.patch
[gaffigan at ak tilecache]$ patch -p0 < tilecache_aoos.patch

Alternatively, I just applied the patch to the TileCache source,
tilecache-2.10.tar.gz, and then repackaged it (zip and .tar.gz).  You
can download one of these and unpack as usual.

http://ak.aoos.org/~gaffigan/tmp/tilecache/tilecache-2.10-gaff.tar.gz
http://ak.aoos.org/~gaffigan/tmp/tilecache/tilecache-2.10-gaff.zip

I have a few notes on using the time support on the page below.  You'll
have to "confirm security certificate" or whatever because we self-sign
our security certificate.

You'll no doubt notice there are a number of other minor patches I've
made, and one new module I've added, which are all bundled together in
the above patch.  When I have some time I want to separate out the time
part again and resubmit it to the mailing list, since I've made a lot of
updates since my original submission.

Hope this helps.  I'd appreciate it if you send me a note if you find
any problems.  If possible I can resolve, or else at least make note of,
the problem.  Thanks.  Hope you find this useful.  TileCache is a great
module.

Steve
