1) What should it do?
When calculating nanos value, underflow may occur if the given time is
near Long.MIN_VALUE. In fact, I'm also not sure what it should do. Just
notice that RI handles the underflow situation in a special/confusing
way, while Harmony does not have any handling.
2) if it's just a single value, why not fix it and never have to deal
w/ it again? Is it an easy fix?
Yes, the fix is quite easy. Do you mean we shall follow RI?
Thanks a lot.

Hello,
I don't think we should bother about single value which is very
unlikely to happpen in real data.

Hello All,
RI's java.sql.Timestamp(long time) behaves confusing when the
parameter time is in Long.MIN_VALUE. Shall we follow RI?
Output of the following sample is:
time: -9223372036854775808
time: 9223372036854775192
timestamp: 292278994-08-17 15:12:55.192
timestamp: 292278994-08-17 15:12:55.192
=========================================
import java.sql.Timestamp;
public class TimeStampTest {
public static void main(String[] args) {
long time = Long.MIN_VALUE;
long time2 = 9223372036854775192l;
Timestamp timestamp = new Timestamp(time);
Timestamp timestamp2 = new Timestamp(time2);
System.out.println("time: " + time);
System.out.println("time: " + time2);
System.out.println("timestamp: " + timestamp);
System.out.println("timestamp: " + timestamp2);
}
