Expected behavior

Dashboard rotation to work

Actual behavior

Dashboard rotation doesn't appear to work.

Steps to reproduce

• Run rev f296609
• Add a second dashboard to config
• Note auto rotation doesn't work even when pressing the play/pause

Actually there isn't any issue with rotation - the problem is that the time is set in ms when in fact it should be seconds.

So this default setting is just exceptionally long and it appears to not be working. Setting something shorter it works fine.
