Standard time keeps noon relatively close to the middle of the day, and midnight pretty close to the middle of the night (which, as the article suggests, is the entire point of having timezones). Summer "daylight time" tweaks that by an hour (or two?) in order to make customary "waking-up time" closer to the summer sunrise. Permanent daylight time just shifts everything over one timezone to the east, which to me seems kind of silly (along the lines of the "these go to 11" bit in Spinal Tap) but does have the benefit of not having to rename things like "the 11 o'clock news".
