Note Submitter: Anonymous ---- I believe the description of the "W" argument is misleading. According to Wikipedia <http://en.wikipedia.org/wiki/ISO_8601#Week_dates>: There are mutually equivalent descriptions of week 01: * the week with the year's first Thursday in it (the formal ISO definition), * the week with 4 January in it, * the first week with the majority (four or more) of its days in the starting year, and * the week starting with the Monday in the period 29 December – 4 January. The missing "in the period 29 December – 4 January" in the parameter description makes its meaning quite different and even wrong.
