! 	 * On WIN32, there is no way to get locale-specific time values in a

! 	 * CP_ACP (see strftime_win32) or UTF16.  Therefore, we get UTF16 and
! 	 * convert it to the database locale.  However, wcsftime() internally
! 	 * uses LC_CTYPE, so we set it here.  See the WIN32 comment near the
! 	 * top of PGLC_localeconv().
