The date/time function need dates enter as date.

i.e. weeknum(2012-09-11;1) you are getting the week of 1905y06m14d (algebraic sum of 2012 - 09 - 11 = 1992 days after 1899y12m31d)

you must use WEEKNUM(DATE(2012;09;11);1)

also WEEKNUM("2012-09-11";1), but this form (date as text) can come in troubles, only can be used when no other interpretation of text is possible (locale language), and with direct references WEEKNUM(B15;1), Not with range functions WEEKNUM(SUM(B10:B15);1), better avoid.
