>Anyway the use of the 24hr notation is pretty recent outside scientific use. Even the military were using a twelve hour clock during WW1. I think only the advent of digital watches made the 24hr notation more acceptable to most people - and I still very rarely hear it used in general conversation. When was the last time you agreed to meet someone at the pub at 2030 hrs ?

A watch? What's that? ;-)

With clocks on the wall, clocks in cars, clocks on computers, clocks on cell/mobile phones, putting something on your wrist to tell time seems quaint to me. The only exceptions I can think of offhand are for referees and other sports officials, who need stopwatches, and maybe someone who is going off into the wilderness with little or no access to electronics. Of course, this group being what it is, I am sure other exceptions will quickly be named ;-) (And that doesn't include people who buy expensive watches to show how much money they have).
