ui.Datepicker: November 2 is present twice in 2008

[h3]

The date november 2 appears twice in 2008 .. it's present on the demo: ​http://docs.jquery.com/UI/Datepicker

This is related to daylight savings time ending on Nov 2nd. Also, reproducibility may be affected by timezone of user and time of day.

The problem is daylight savings time. The Date object sets the year,month and day, but with no time specified defaults to midnight. So when the time increments by 1 day, and then daylight savings sets it back 1 hour, you get two November 2 on the calendar. Include a time greater than 1 when the date object is created and problem is solved.

Change line 1272 in ui.datepicker.js or line 5801 in jquery.ui.all.js from:

var printDate = new Date(drawYear, drawMonth, 1 - leadDays);

to:

var printDate = new Date(drawYear, drawMonth, 1 - leadDays,12);
