TIMEPLOT: Problem with incorrect year display

[GoogleCodeExporter]

What steps will reproduce the problem?
1. simile-timeplot/src/webapp/site/tests/time_geometries/index.html
2. The years are incorrectly displayed!

What is the expected output? What do you see instead?

The first year marker should be for 2008, since the first event is in mid-2007.

What version of the product are you using? On what browser and what
operating system?

Firefox 3.0.8, Ubuntu Intrepid, computer is set up to use CEST (Rome) time.

Please provide any additional information below.

Please find attached a file displaying exactly how I see the results of the
time_geometries test.

Any chance of this fix being applied to the core hosted distribution at
http://static.simile.mit.edu/timeplot/api/1.0/timeplot-api.js ?

This bug can be also observed in the Timeplot tutorial at
http://www.simile-widgets.org/timeplot/docs/

1) Look at the Timeplot resulting from tutorial step 10.
2) Notice that, e.g., the range of dates from year 2006 is labeled as year 2005.

Workaround = fix _calculateGrid (using the patch from comment #2) before 
instantiating 
DefaultTimeGeometry:

  function onLoad() {
      var eventSource = new Timeplot.DefaultEventSource();

      Timeplot.DefaultTimeGeometry.prototype._calculateGrid = function() {
      ...
                    case time.CENTURY:
                    case time.MILLENNIUM:
                      var tmpd = new Date(t.getTime());
                      tmpd.setDate(t.getDate() + 1);
                      var l = tmpd.getUTCFullYear();
                      break;
      ...
            return grid;
      };
