Vancouver's Olympic Countdown Clock seems to be getting ahead of itself.

The 2010 timepiece is running almost a day in advance. On Wednesday afternoon, the clock showed 400 days to go before the start of the Winter Games. It should have been 401. The clock hasn't been totally correct since December.

In November, it broke down and took a week to repair.

The clock was unveiled before a crowd of 2,000 at its location in front of the Vancouver Art Gallery in February, 2007. It was made by famed Swiss watchmakers Omega, who will be responsible for the scoring and competition results during the Games.

The opening ceremonies for the 2010 Winter Olympics begin on Feb. 12, 2010 -- at 6 p.m. Adjust your watches now.
