Setting timestamp to current time in Java

Question

I'm trying to set the current datetime in a java EE7 web app to an apache derby database I have.

I'm using timestamp in both java and derby so I don't have to worry about type conversions.

However, the only way I know of to get the current datetime is through calendar.set(Calendar time).

Is there inherent way to set the current datetime for timestamp or will I need to use a converter?

In SQL, there is CURRENT_TIMESTAMP: http://db.apache.org/derby/docs/10.11/ref/rrefsqlj15866.html#rrefsqlj15866 — Bryan Pendleton, Aug 25 '15 at 13:56

You can use the Date class for initializing to the current time , i.e :

Timestamp timestamp = new Timestamp(new Date().getTime());

The java.util.Calendar class is an abstract encapsulation of the Date object. Calendar provides getter and setter for the date fields , nothing more. And it comes at a cost.

In your case using a simple Date is ideal.

You are welcome! Remember not to use Calendar unless you absolutely need it. It comes with some overhead. – Laurentiu L. Aug 25 '15 at 13:23

use joda jar and import the required packages.

DateTime d = new DateTime().withZone(DateTimeZone.forID(TIME_ZONE));
