If we agree this is a reasonable thing to do, then here is CL: http://crrev.com/2691003002. I'd also be interested in re-deploying the app myself to get experience contributing to Milo, but please let me know whether I need do to anything beyond running gae.py and flipping the active version to avoid breaking the world.

Since this is an aesthetic change, it's hard to know the impact without screenshots :).  So uploading a tainted version and attaching a screenshot would be the right course.

I vaguely remember doing this before but scrapped the idea because the timestamps became overtly long.

There's nothing special about milo that wouldn't work with gae.py.  There's a shortcut in the makefile so that if you run "make up" then it'll call gae.py and pass in the default args for you, but that's optional.

lgtm, I was always in favor of doing this for the same reason - glad we're fixing it. :)

 Issue 692309  has been merged into this issue.

Please just always put a timezone rather than "local time". "local time" doesn't mean anything, it is never clear who the "local" is? Is it local to the bot, local to the appengine app, the browser, the user's preferences, who!?

"US/Pacific", "PDT" or "+10:00" is clearer and exact.

Unfortunately we can't derive the exact timezone name from the browser, but +10:00 is doable.

I personally prefer +/-<amount> as you then don't have to look up the offset :-)

Done. CL and tainted versions are updated.
