   Sets the current strategy for dealing with wall times that are repeated
   whenever the clock is set back during dailight saving time end transitions.
   The default value is <constant>IntlCalendar::WALLTIME_LAST</constant> (take
   the post-DST instant). The other possible value is
   <constant>IntlCalendar::WALLTIME_FIRST</constant> (take the instant that
   occurs during DST).
  </para>

   This function requires ICU 4.9 or later.
