Pls help, can't find the DurationtoYears block from my clock component.

You do not find it because it does not exist

Duration(start,end)
Returns the milliseconds by which end follows start (+ or -)

Calculate the milliseconds of a year, which is 1000 x 60 x 60 x 24 x 365 and use the Duration nethod divided by that number
