The top-left calendar tab and the date picker in various dialogs shows two months with the title March 2006 in a row, one of which clearly being February 2006. On #calendar there seems to be a clue it would occur when the day is > 28.

Reproducible: Always

Steps to Reproduce:
1. Open Sunbird. (Today is the 29th.)
2. Click on the Date tab (top-left).
3. Browse to 2006.

Actual Results:  
There are two March 2006 in a row, one for February and one for March.

Expected Results:  
There should be one February 2006 and one March 2006.

Confirmed in 20051127 nightly only when the operating system's current date is > 28.

We're getting a js-date rollover somewhere in minimonth.xml.  Since the current date is > 28, setting the month to be february results in march actually appearing when js-date corrects itself.  I suspect you might see something similar if the current date was 31 in months of only 30 days.

Ensure that day of month is <28 for tempDate to avoid rollover.
