Clock
The leap second keeps atomic clocks (and therefore computers and cell phone networks) on the same cycle as the Earth’s rotation. - 

From the Marketplace Datebook, here’s an extended look at what's coming up next week:

 

  • Why can't Daylight Saving Time begin on a Friday at 4 p.m.? That’s when I'm ready to spring forward.
  • Forty-nine years ago Neil Simon’s "The Odd Couple" bowed on Broadway. Several versions have followed for film and TV and stage. (Because you can't get enough of a bad roommate.)
  • On Tuesday, two swell guys celebrate birthdays. Barbie's boyfriend Ken turns 53. And "Jackass" star Johnny Knoxville turns 43. (Meaning they're both Pisces.)
  • Midweek we get a look at the nation's balance sheet. The Treasury Department issues its monthly statement for February.
  • On Thursday, the Commerce Department reports on retail sales for February.          
  • On Friday, the Labor Department releases its Producer Price Index.
  • And with all the change in our lives it's nice to know that there is a constant. A mathematical constant, that is. 3-14 or March 14 is Pi Day.
