You're not paying attention. =) The locale information is used for both
input and output (see 'man strptime' for example). The point was, why
bother re-telling *subversion* that you prefer date format A over date
format B when the OS *already* knows this information, and can tell
subversion if/when it asks.

I'm not going to restate the entire context of the discussion here.
There are archives of the thread.
