Hi all,

I'm trying to work with an existing database where they have stored date/time information as a Long Integer in the database.

I'm trying to figure out the best way to use a Custom Type in the Entity Model so the app sees the attributes as NSTimestamps.

I've subclassed NSTimestamp and added a method to convert the db value to it when read, which works, but getting it to write a Long back to the database is what I'm struggling with.

I'm sure it is something simple, but I'm just not seeing it.

Here is how I do something very similar to this:

package net.onthenet.datatypes;

import com.webobjects.foundation.NSTimestamp;

public class UnixTime extends NSTimestamp {

	public UnixTime(NSTimestamp ts) {
		super(ts);
	}

	public UnixTime(long l) {
		super(l * 1000);
	}

	public static UnixTime valueOf(String value) {
		return new UnixTime(Long.valueOf(value).longValue());
	}

	public static UnixTime valueOf(Long value) {
		return new UnixTime(value);
	}

	public String toString() {
		return new Long(getUnixTime()).toString();
	}

	public long getUnixTime() {
		return getTime()/1000;
	}
}
