I tried it, changed the values the max low position seems to be the 41 as you say in the script but it crosses with the text using kaznelsoft margins hack.
It's possible to show only Hour and minutes?
It's possible to put the clock in a lower position?
Great job.
I answer myself the first question, change %T for %H:%M to see Hour an minutes but not seconds.
