Sometimes Old Technology is Better  
I know time is in some sense relative but since getting a new digital radio, while still keeping my old FM radio in the kitchen, I've noticed that the pips for the time on the hour aren't simultaneous. The digital signal is behind.

This morning David Rooney, curator of timekeeping at the Royal Observatory in Greenwich, was on Saturday Live. A listener emailed in on this topic. Apparently the FM radio (old technology) is correct. What happens, I wonder, if we all go digital?

Ditto, I can't see it being a huge deal. We all end up two or three seconds late, or they adjust the broadcast signal to suit. I suspect the world won't end...

No but it is maybe less real. More fake digital.

Fake digital? Give me a DAB radio over FM any day of the week!

I suppose 3 seconds only matters really if you're an Olympic athlete - but I used to set my watch by the pips!

I suspect however that the built-in time signal that travels over digital radio is accurate.

Currently, digital radio is taken from the same source as FM, but has to be encoded and decoded at either end - given in particular that most consumer DAB radios use cheap and slow processors, this does introduce noticable delay.

The world slows down :D

If would be nice if it was cumulative.

Give us back the 3 seconds!

(I can argue calendars too).

Apparently an extra 'leap second' will be added onto the final minute of 2008.
