(tz) API: define "user.timezone" property

Currently, the "user.timezone" property is not defined at the API level, which sometimes creates confusion to developers.

:::::
os.version = 4.0
user.home = C:\WINNT\Profiles\weinert
user.timezone =
java.awt.printerjob = sun.awt.windows.WPrinterJob
file.encoding = Cp1252
java.specification.version = 1.4
:::: etc. pp


System property user.timezone has no (empty string) value.

This breaks or disables all applications depending on this info.

Most JDKs 1.3.x and earlier have this fault.

By the way The latest version, knowing the time zone, was 1.3 beta.
