Format Date/Time String Function

[DzeiPee]

I found some odd behaviour in LabView 2010 Format Date/Time String Function. It does return wrong 07 week number, when it should today (20.2.2013) retun week 08. Time format string is "%W%y". Has somebody found solution how to go around the problem?

It is doing what it says it will do, please read the help: http://zone.ni.com/reference/en-XX/help/371361G-01/glang/codes_for_time_format_str/

Excerpt from the help:

<%W>	week number of the year (00–53), with the first Monday as the first day of week one; 00 represents the first week

help says : 

<%W>	week number of the year (00–53), with the first Monday as the first day of week one; 00 represents the first week

EDIT :

Damn a second too late

Be advised that the %W and %w date formatters in LabVIEW are not ISO-8601 compliant.

There is a link in this example to a thread containing info about calculating an ISO-80601 week number.
