also known as "daylight savings time," true time is the clock setting that keeps the sun from setting in mid-afternoon in the winter. The alternative to true time is daylight wastings time (which some, especially morning people, refer to as "standard time").
No clock setting that puts sunset in mid-afternoon is "standard." True time is what we use in the summer, and daylight wastings time is the clock setting forced upon us by morning people in the winter. Then, morning people revel in making the rest of us get up an hour earlier to get back to true time.
