[Martin Buchholz]

No actual bugs fixed, but good to stamp out all instances of new Date(1970)

8247706: Unintentional use of new Date(year...) with absolute year
https://cr.openjdk.java.net/~martin/webrevs/jdk/Date-constructor-1900/
https://bugs.openjdk.java.net/browse/JDK-8247706

The "1990" below looks like a simple typo:

-        Date d = new Date(2003 - 1990, OCTOBER, 31);
+        Date d = new Date(2003 - 1900, OCTOBER, 31);
