Summer Time Problem - infinite loop

[Marco La Porta]

I have an infinite loop in function parseTimeRange when min-max date range includes a summer-time change.
I explain better: in italy summer-time start in march 25th, 2012, at 2.00 am .
If I pass to jqgantt json data including date from march 1st, 2012 to march 31th, 2012 code loops indefinitely in lines 1353-1362:

parseTimeRange: function(from, to, scaleStep) {

var current = new Date(from);

var end = new Date(to);

var ret = new Array();

var i = 0;

do {

ret[i] = new Date(current.getTime());

current.setHours(current.getHours()+scaleStep);

current.setHours(Math.floor((current.getHours()) / scaleStep) * scaleStep);

if (current.getDay() != ret[i].getDay())

current.setHours(0);

i++;

} while (current.getTime() <= to.getTime());

return ret;

},

In above lines , when current is "Sun Mar 25 2012 01:30:00 GMT+0100" the statement
current.setHours(current.getHours()+scaleStep); does not increment current.
