[Bug classpath/28550] New: TimeZone.getDefault() probably incorrect and not equals(`/etc/localtime`)

[andrew at operationaldynamics dot com]

The default ("local") timezone returned by TimeZone.getDefault() should match
the  name of the zone pointed at by the /etc/localtime symlink [or named in the
first line of the an /etc/timezone file, which is a long since deprecated
usage]

On our office systems, /etc/localtime -> /usr/share/zoneinfo/Australia/Sydney
(and just for kicks, /etc/timezone = "Australia/Sydney")

$ java TimeZoneBugs
Local zone:                                             Australia/Sydney
(correct)

For zone named:                                         America/Montreal
TimeZone.getID() should be the same:                    America/Montreal

For zone named:                                         Australia/Sydney
TimeZone.getID() should be the same:                    Australia/Sydney

For zone named:                                         Europe/Paris
TimeZone.getID() should be the same:                    Europe/Paris

You can observe that the TimeZone returned with
.getTimeZone("Australia/Sydney") matches .getDefault() ... and even more
importantly, they match with .equals()

But with classpath, things are confused. JamVM 1.4.3 + classpath 0.91:

$ jamvm TimeZoneBugs
Local zone:                                             AET
(wrong!)

For zone named:                                         America/Montreal
TimeZone.getID() should be the same:                    America/Montreal

For zone named:                                         Australia/Sydney
TimeZone.getID() should be the same:                    Australia/Sydney

For zone named:                                         Europe/Paris
TimeZone.getID() should be the same:                    Europe/Paris

With GCJ 4.1.1 the same problem arises:

$ ./TimeZoneBugs
Local zone:                                             AET
(wrong!)
etc
