Starting with the first energy crisis (as I recall it) in the Nixon years, the starting date for Daylight Saving Time has been monkeyed with repeatedly. Until the early 1970s, it started at 2:00 AM on the last Sunday of April and ended at 2:00 AM on the last Sunday of October. Now it starts in mid-March, at which point it's absurd (outdoor activities are still rather hampered by weather) and ends in early November (ostensibly for safety on Hallowe'en). By contrast, in the years between the world wars, Daylight Saving Time wasn't observed at all.
So, how do we get things back to a situation where standard time is, indeed, standard? Let's say Daylight Saving Time wouldn't begin until 2:00 AM on the first Sunday in May (by which time it makes sense with respect to weather and the duration between sunrise and sunset) and end at 2:00 AM on the last Sunday in September (duration between sunrise and sunset is less than 12 hours by then). That puts the warmer months (May-September inclusive, roughly; 147 days) on Daylight Saving Time and the balance of the year (218 days in non-leap years) on standard time.
