Retrieving wrong date/time with Timestamp

[Gustavo Santos]

Hi everyeone,

I'm stuck with it trying to figure out what's going on and I thought somebody in here could help me out...

  	    // get current moment in default time zone
	    DateTime dt = new DateTime();
	    // translate to Sao Paulo local time
	    DateTime dtSP = dt.withZone(DateTimeZone.forID("America/Sao_Paulo"));
            // prints out just fine...
	    System.out.println(dtSP);
	    // convert it to Timestamp
	    Timestamp timestamp = new Timestamp(dtSP.getMillis());
            // still gets the current time zone instead of the one I've defined above!
	    System.out.println(timestamp);  

When I convert it to Timestamp I still get a different time than the timezone I've specified:

2010-01-18T13:29:57.864-02:00

2010-01-18 10:29:57.864

What class is DateTime? I'm not familiar with it and I can't find it. I know java.util.Date, java.sql.Date, java.sql.Time, java.sql.Timestamp but not DateTime

I was having a similar problem. I searched the JavaDocs but couldn't find a DateTime class...

I'm sorry guys, I think I forgot to mention that I'm using Joda Time which is where I get the DateTime class from.

I don't know Joda Time, but here's what I see in that code. You have one object which is a kind of date. You assign the São Paulo time zone to it. Next you create a second object which is also a kind of date, but you don't assign the São Paulo time zone to it. Therefore its time zone is whatever your default time zone is, or whatever the default time zone for a Joda object is. Not the same time zone? Then you shouldn't be surprised that they appear differently.
