Our client's site: http://mountaintimes.info is throwing an XSLT error as of February 1. 

The problem we're having occurs when the call in the XSLT to pdcalendar:GenerateDates is passed a start date greater than February 1st, 2012.

 

 In our case, a call like:

 

 <xsl:variable name="messages" select="pdcalendar:GenerateDates('2012-01-31','2012-12-31','event')" />

 

 would work, but when it rolls around to February:

 

 <xsl:variable name="messages" select="pdcalendar:GenerateDates('2012-02-01','2012-12-31','event')" />

we get the following error:

 

Error parsing the XSLT:

System.Xml.Xsl.XslTransformException: An error occurred during a call to extension function 'GenerateDates'. See InnerException for a complete description of the error. ---> System.FormatException: String was not recognized as a valid DateTime. at System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles) at PDCalendar.library.[1](String [1], String

This happens even when there are no published events. 

This happens even when using the default PDCalendar XSLT.

Could this be because this is a leap year?
