Datepicker: October 2010 only shows a few dates for Russian timezone [Safari]

[sekerin]

This bus can be reproduced on Mac OS 10.8.2, Safari 6.0.1. Steps to reproduce:

• open datepicker
• pick a date earlier than october 2010
• try to choose a later date by clicking the right arrow

Result: Datepicker "stuck" on october and only 2 first days of october are displayed

Hi sekerin,

Thanks for taking the time to contribute to the jQuery UI project. I'm not seeing the issue you're describing on the default datepicker demo at ​http://jqueryui.com/datepicker.

Can you please post a reduced test case that shows this issue. You can use this as a boilerplate to get started - ​http://jsfiddle.net/tj_vantoll/tRdpr/.

Thanks.

Hi

I don't understand why you can't reproduce this issue, because it reproduces perfectly on ​http://jqueryui.com/datepicker with default settings. Recently I tested datepicker on iPad and it shows same behavior. By the way, I forgot to mention that January 2010 in datepicker consists only 1 January. And this issue reproduces on the same environment.

We've had multiple people test this, and we cannot reproduce this. What timezone setting are you using in OS X?

Hi Thanks for your patience. This issue doesn't depend on timezone. It depends on country. When I choose a timezone for Russia the issue reproduces. I guess the problem is that daylight saving time is canceled in Russia.

Confirmed by setting my timezone to Moscow Standard Time. October 2010 is completely broken, not just the navigation. This is limited to Safari.
