Description
The customer reports that in 2038, DST should start from 2038/03/14 AM 2:00. However, all JDK versions seem to have 2038/03/14 AM 4:00 as the starting time for the year 2038 and later.
Reproducer:
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
public class DSTTest {
public static void main(String[] args) {
try {
TimeZone timeZone =
TimeZone.getTimeZone("America/New_York");
SimpleDateFormat sdf = new
SimpleDateFormat("yyyy/MM/dd HH:mm:ss:SSS");
Long time = 0L;
sdf.setTimeZone(timeZone);
time = sdf.parse("2037/3/8 01:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2037/3/8 02:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2037/3/8 03:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2037/3/8 04:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2038/3/14 01:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2038/3/14 02:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2038/3/14 03:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
time = sdf.parse("2038/3/14 04:30:00:000").getTime();
System.out.println(sdf.format(new Date(time)));
} catch(ParseException e) {
System.err.println(e.getMessage());
}
}
}
