Question

I am trying to get the timestamp.

This works.

final Calendar cal = new GregorianCalendar(tz);
final Timestamp ts = new Timestamp(cal.getTimeInMillis());

But, I don’t want to reinstantiate the variables each and every time, I need to get the timestamp. How can I do that?

I tried to do..

//instantiate the variables.

    private final Calendar cal = new GregorianCalendar(tz);
    private final Timestamp ts = new Timestamp(cal.getTimeInMillis());

Inside a method()

    // trying to ask calendar to recalculate the time -- not working.
    cal.setTimeZone(tz); // I tried cal.clear() but it is giving me time during 1970 which I don't want.
    ts.setTime(cal.getTimeInMillis());

This doesn’t seem to work. Could you suggest?

Try System.currentTimeMillis() to avoid creating a calendar.
