It seems that w (and uptime) are the only (?) utilities in the tree that
force a 12 hour clock representation.

I wondered if there are any standards requiring this?

Furthermore, when I started to look for a bettter way to do it, I found
(to my surprise) that strftime offers apparently nothing better than %X
(or NetBSDs locale subsystem is not yet good enough to make %X into 
a 12 hour display in locales that prefer this).

Not that I realy care - just curious...
