Show week numbers in the digital clock settings?

How do I include the iso weeknumbner in the digital clock appearance?

there does not appear to be a week function in the time/date spec used by Qt

the calendar app must somehow calculate these values

found this in the calendar main.qml

Plasmoid.nativeInterface.weekNumber(d)

that seems to handle this calculation.

so there is potentiality a .qml hack of the digital clock that could display this vaule, but .qml programing is over my head.

Oh thanks. Something to investigate. It is amazing how much the academic world depends on (ISO) weeknumbers…
