I would except I have to fight with Brane first. ;-)

And how would you propose that we add precision to the existing call? I
agree with you that being able to match timestamps in an intelligent and
configurable fuzzy way would be vastly superior to the existing hard
cut, but I don't see how to do that.

What about something like this:

        svn log -r{2005/08/30}:{2005/08/30}

would return all log commits on that date (regardless of time). And this:

        svn log -r{"2005/08/30T1530"}:{"T0001"}

would return all commits in the full minute of 15:30, just like this would:

        svn log -r{"2005/08/30T1530"}:{"2005/08/30T1531"}

Is that a hard veto or a "we haven't discussed this sufficiently yet"
veto of what Sussman suggested? Would you have less argument with
something that resolved some subsecond precision but abandoned the
fiction of the current scheme (I'm thinking precision to 100ths of a
second)?
