Summary

In <time.h>, strftime conversion specifiers %U, %W, and %V do not need tm_year.

Committee Response

The Standard is correct. tm_year is provided in the case %U and %W, to give freedom to choose the implementation (the output can be determinded using either tm_year or tm_wday, along with tm_yday). For %V it is definitely required as the computation cannot be made without tm_year.
