/*
* Preferred strftime(3) format specifier for printing timestamps in pg_dump
* and friends.
*
* We don't print the timezone on Windows, because the names are long and
* localized, which means they may contain characters in various random
* encodings; this has been seen to cause encoding errors when reading the
* dump script. Think not to get around that by using %z, because
* (1) %z is not portable to pre-C99 systems, and
* (2) %z doesn't actually act differently from %Z on Windows anyway.
