 When a recurring event is established using the WP cron functions the
 function takes a Unix timestamp and a recurrence interval.

 In the situation where daylight saving changes the local time, the timing
 of an event can change by an hour. So, if a database backup is set to run
 at midnight when the clocks change this can start to happen at 11pm or 1am
 instead since the timing of the event is based on an initial static time
 (Unix timestamps reference point is January 1, 1970) and a static interval
 period.

 An enhancement to the cron functions would be to account for an obey
 daylight saving changes so that events schedule for midnight actually
 occur at midnight irrespective of the time of year.
