Yes, that is correct. The whole purpose of apr_implode_gmt is to always
return a UTC apr_time_t.

I'm looking at svn_fs__dag_commit_txn right now, and the code to
calculate the timestamps looks O.K.

Don't know.

Can you please do one thing: go to apr/test, `make testtimg &&
./testtime'. If it fails one of the apr_implode_* tests, make a note of
the difference it prints It may be something specific to your platform
-- FreeBSD, right? Although, all BSDs have tm_gmtoff; if that isn't set
correctly, all bets are off.

If it *doesn't* fail, fire up GDB and fix libsvn_fs, is all I can say. :-)
