If millisecond precision is adequate for your application, you can use
java.util.Date. Your code with java.util.Date might look something
like this:
//Format the timestamp
DateTimeFormat timestampParser = DateTimeFormat.getFormat
("yyyy-MM-dd HH:mm:ss.SSS");
Date newOrderTimeStamp = timestampParser.parse("2009-03-10
22:30:29.000");
DateTimeFormat timeFormat = DateTimeFormat.getShortTimeFormat
();
Label newOrderTimeStampLabel = new Label(timeFormat.format
(newOrderTimeStamp) + " ");
//Calculated minutes passed since order submitted
Date currentTimeStamp = new Date();
long currentTime = currentTimeStamp.getTime();
long tsTime = newOrderTimeStamp.getTime();
long calculatedTime = currentTime - tsTime;
long minutesSinceOrderSubmittedLong = (calculatedTime /
1000) / 60;
Label minutesSinceOrderSubmittedLabel = new Label
(minutesSinceOrderSubmittedLong + " minutes ago");
Be careful if you need to do this kind of calculation frequently,
however. Javascript does not support longs natively, and so GWT ( >
1.5) emulates longs with two integers. While this emulation is
correct, it also is slow. If performance is a concern with this code,
you may want to consider using doubles for the calculation instead.
