Many people will be sleeping an extra hour when Daylight Saving Time ends at 2 a.m. Sunday.  A fair number will forget to change their clocks on Sunday as well.

Even with the luxurious extra time to snooze, fewer people are in support of the clock-changing tradition. According to a recent Rasmussen Reports survey cited in the Los Angeles Times, 37% of Americans think the time change is a good idea, down from 45% last year.

The "spring forward" and "fall back" practice was originally implemented to save energy. 

About 70 countries now participate, although in the U.S., Arizona and Hawaii do not.

Should we do away with Daylight Saving Time?  The debate continues to grow.
