java.sql.Timestamp implementation of Google Android API 10 2.3.3

Question

Code:

import java.sql.Timestamp;
Timestamp startTimestamp = new Timestamp(2012, 1, 1, 0, 0, 0, 0);
System.out.println("startTimestamp = " + startTimestamp);
System.out.println("startTimestamp.getYear() = " + startTimestamp.getYear());

Output:

startTimestamp = 3912-02-01 00:00:00.0
startTimestamp.getYear() = 2012

Is it a bug or am I doing something wrong?

The javadoc says:

Parameters: year - the year minus 1900

So, 2012+1900=3912.

Note, that new Timestamp(2012, 1, 1, 0, 0, 0, 0); is deprecated and I think is the root of your problem!

Use Timestamp startTimestamp = new Timestamp(System.currentTimeMillis()); instead.

Also, note that startTimestamp.getYear() is also deprecated!

Deprecated. As of JDK version 1.1, replaced by Calendar.get(Calendar.YEAR).

Returns the day of the month represented by this Date object. The value returned is between 1 and 31 representing the day of the month that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone.

Consider this example (based on your original code):

public static void main(String[] args)
{
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.DAY_OF_YEAR, 1);
    cal.set(Calendar.MONTH, 1);
    cal.set(Calendar.HOUR, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);
    Timestamp startTimestamp = new Timestamp(cal.getTimeInMillis());
    System.out.println("startTimestamp = " + startTimestamp);
    Calendar cal2 = Calendar.getInstance();
    cal2.setTimeInMillis(startTimestamp.getTime());
    System.out.println("Year = " + cal2.get(Calendar.YEAR));
}

It would produce output:

startTimestamp = 2012-01-01 12:00:00.0
Year = 2012
