                PR classpath/28550
                * java/util/Date.java (parse): Properly parse 09:01:02 as
                hours/minutes/seconds, not as hours/minutes/year.
                * java/util/SimpleTimeZone.java (SimpleTimeZone): Simplify
                {start,end}TimeMode constructor by calling shorter constructor,
                set {start,end}TimeMode fields after it returns.
                (setStartRule): Don't adjust startTime into WALL_TIME.  Set
                startTimeMode to WALL_TIME.
                (endStartRule): Similarly.
                (getOffset): Handle properly millis + dstOffset overflowing
into the
                next day.  Adjust startTime resp. endTime based on
startTimeMode
                resp. endTimeMode.
                * java/util/TimeZone.java (zoneinfo_dir, availableIDs,
aliases0): New
                static fields.
                (timezones): Remove synchronized keyword.  Set zoneinfo_dir.
                If non-null, set up aliases0 and don't put anything into
                timezones0.
                (defaultZone): Call getTimeZone instead of timezones().get.
                (getDefaultTimeZone): Fix parsing of EST5 or EST5EDT6.  Use
                getTimeZoneInternal instead of timezones().get.
                (parseTime): Parse correctly hour:minute.
                (getTimeZoneInternal): New private method.
                (getTimeZone): Do the custom ID checking first, canonicalize
                ID for custom IDs as required by documentation.  Call
                getTimeZoneInternal to handle the rest.
                (getAvailableIDs(int)): Add locking.  Handle zoneinfo_dir !=
null.
                (getAvailableIDs(File,String,ArrayList)): New private method.
                (getAvailableIDs()): Add locking.  Handle zoneinfo_dir != null.
                * vm/reference/java/util/VMTimeZone.java
(getDefaultTimeZoneId):
                To read /etc/localtime, use ZoneInfo.readTZFile instead of
                VMTimeZone.readtzFile.  Get better timezone name for
                /etc/localtime, either if it is a symlink or through
                /etc/sysconfig/clock.
                (readSysconfigClockFile): New static method.
                (readtzFile): Removed.
                * gnu/java/util/ZoneInfo.java: New file.        
                * java/lang/System.java: Add gnu.java.util.zoneinfo.dir to
comments.
                * NEWS: Documented TimeZone interface changes.
