TLB Clock skinning - parameter for month in digits needed

I need to make the skin show dates like "22.07.04". I haven't got any problems with date and year(BTW, [background clock]->coord_year parameter for year coordinates isn't listed on tlbclock.php!!!). But the month is another tale... When I'm using [background clock]->coord_month, plugin shows months data from months names image([images]->month).
I really don't want to remake [images]->month file and put digits instead of "Jan","Feb" etc there. Is there any parameter to show month number in digital form?
