Example 6 with UResourceBundle

the class ZoneMeta method countEquivalentIDs.

 * 0.  This means either the given ID is not a valid zone, or it
 * is and there are no other equivalent zones.
 * @param id a system time zone ID
 * @return the number of zones in the equivalency group containing
 * 'id', or zero if there are no equivalent zones.
 * @see #getEquivalentID
