Subject: [PATCH] move cluster maintenance window
To avoid GMT/BST issues, move the maintenance window from 4-8AM UTC to
1-5AM UTC.
Google requires that the window be at least 4 hours and so this is
different from the 2-5AM specified by #11.
Take the opportunity to tidy up the recurrence specification and to
choose a rounder arbitrary date for the start time.
Closes #11
