How daylight savings time REALLY works.

1. Wait until the last minute before releasing patches, notifications and alerts to your customers and endusers.
2. Get your IT staff (or better yet somebody else's) to apply the patch out of business hours, preferably after you have worked your evening overtime, so say 10pm BUT before 11.30 when the backup kicks in.
3. Hey presto, your IT staff are too tired as they were working late so they sleep in and therefore don't use any extra electricity or energy whilst they are in bed in the morning instead of being at work - et voila - you have saved some energy.
