Re: JDBC/TIMESTAMP/infnity question

For anyone who happens to find this via google search:

I did a little research and experimenting and found the answer. Java
doesn't include the era in the String version of the date by default,
so in the example below, the date of 292269055-12-02 is actually BC,
which is pretty reasonable.
