In doc/DETAILS, it says that soon GnuPG will migrate to an ISO time
format.  What are the motivating reasons for this?  What's the timeframe
for the changeover?  I've seen this warning in the DETAILS file for
quite some time, so I'm kind of wondering if that's still the plan or if
it's been forgotten about.
