Because we need to choose a format. And the ISO 8601 format is actually
defined as the European standard (dunno about US). Maybe as a US guy, you
might want alphanumeric day/month in there, but that isn't going to work
well in a universal context.
In short, we need a format that works "everywhere" and ISO 8601 is the best.
The particular format Karl has proposed *is* compatible with ISO 8601 up to
the parenthesized portion.

/bin/bash has a very hard time accessing those libraries. A *lot* of
scripting is going to be by invoking the command-line client. As much as I
would agree with you on "use the libraries", I just don't think they'll be
used as often as I'd like.
Yes, we'll have bindings for Perl and Python and others. But will everybody
have those bindings installed? I'd posit a much lower percentage than those
who have the cmdline client. Thus, script writers will tend towards wrapping
the client.

The TZ must be appended. Without it, the user doesn't know if the displayed
time is local time, or UTC.

They get stored into the repos in UTC. When Sander runs 'svn log', he gets
all the times displayed in +0100 (or whatever his TZ is). That is, they are
adjusted to his local time.

Nope. See above. It is needed to say, "I've translated this to your time."
