Hmm I believe I've seen this on TV but I've never actually called any numbers to find out what the time was.
I guess it's kinda a money sink for them at this point since the majority of people nowadays have cell phones or PDAs.
Though, on a side note, I wish that people still wore pocket watches, those were probably the coolest form of watch I know of and I just can't bring myself to wear one like they did back in the ole days
