 844:    * Maps a time zone name (with optional GMT offset and daylight time

 847:    * or <code>getDefaultTimeZoneId()</code>.  Note that giving one of
 848:    * the standard tz data names from ftp://elsie.nci.nih.gov/pub/ is
 849:    * preferred.  
 850:    * The time zone name can be given as follows:
 851:    * <code>(standard zone name)[(GMT offset)[(DST zone name)[DST offset]]]
 852:    * </code>
 853:    * <p>
 854:    * If only a (standard zone name) is given (no numbers in the
 855:    * String) then it gets mapped directly to the TimeZone with that
 856:    * name, if that fails null is returned.
 857:    * <p>
 858:    * Alternately, a POSIX-style TZ string can be given, defining the time zone:
 859:    * <code>std offset dst offset,date/time,date/time</code>
 860:    * See the glibc manual, or the man page for <code>tzset</code> for details
 861:    * of this format.
 862:    * <p>
 863:    * A GMT offset is the offset to add to the local time to get GMT.
 864:    * If a (GMT offset) is included (either in seconds or hours) then
 865:    * an attempt is made to find a TimeZone name matching both the name
 866:    * and the offset (that doesn't observe daylight time, if the
 867:    * timezone observes daylight time then you must include a daylight
 868:    * time zone name after the offset), if that fails then a TimeZone
 869:    * with the given GMT offset is returned (whether or not the
 870:    * TimeZone observes daylight time is ignored), if that also fails
 871:    * the GMT TimeZone is returned.
 872:    * <p>
 873:    * If the String ends with (GMT offset)(daylight time zone name)
 874:    * then an attempt is made to find a TimeZone with the given name and
 875:    * GMT offset that also observes (the daylight time zone name is not
 876:    * currently used in any other way), if that fails a TimeZone with
 877:    * the given GMT offset that observes daylight time is returned, if
 878:    * that also fails the GMT TimeZone is returned.
 879:    * <p>
 880:    * Examples: In Chicago, the time zone id could be "CST6CDT", but
 881:    * the preferred name would be "America/Chicago".  In Indianapolis
 882:    * (which does not have Daylight Savings Time) the string could be
 883:    * "EST5", but the preferred name would be "America/Indianapolis".
 884:    * The standard time zone name for The Netherlands is "Europe/Amsterdam",
 885:    * but can also be given as "CET-1CEST".
