Comment (by ryandesign):

 Buildmaster is now being started with `TZ=UTC`. The waterfall view seems
 to be respecting that at least.

 Does this look good enough or should we try to start the buildworkers with
 that setting as well? I'm not sure if that would actually do anything.

 The MacPorts logs on the workers do still contain embedded timestamps that
 MacPorts puts there; if we wanted those to be UTC we probably really would
 have to set the system timezone to UTC on the buildworkers (which would be
 ok).
