>Description:

On NetBSD 5.2:
$ TZ=America/Los_Angeles date -d "25-may-2013 14:00utc" +"%A %B %d %I:%M %p %z"
Saturday May 25 07:00 AM -0700

But on NetBSD 6.0:
$ TZ=America/Los_Angeles date -d "25-may-2013 14:00utc" +"%A %B %d %I:%M %p %z"
Saturday May 25 03:00 PM -0700

Notice the hour and am/pm are wrong for newer date.
(Timezone offset is correct.)
