Thanks for 1,2 and 4. Fixed.

The 3) is not true. below these lines later we decrement the mouth value.

I setup the formatoptions.srcformat on my date column as 'F, d Y H:i:s' and the formatoptions.newformat as 'm/d/Y'

My result is 01/31/2009, but should be 03/31/2009.

I have tracked the issue down to the jquery.fmatter.js file, lines 110 - 126.  I found several issues.

1) Line 110 & 111: The regex for date & format variables does not account for a comma.  Adding \, seems to address this.

2) Line 119 & 120: Nothing ever uses the 'dM' variable.  I altered this to instead set the result to 'date[k]'.

3) Line 120: Adding +1 to the numeric month gives incorrect result.  JS months are zero based 0-11.  I removed the +1.

4) Line 126: In my format, I did not use 'm', I used 'F'.  There is no code to set 'm' from 'F' once the numeric month has been determined.  I added a line before this of 'if (ts.f) {ts.m = ts.f;}'.

Making these 4 alterations addresses the issue I found.

Thanks
