@ajvb I'm interested in potentially fixing these points but I don't totally understand them. Could you drop a quick note as to what you meant by these?
From my perspective:
Do you mean that daylight savings time shifts are not accounted for? As in a job scheduled for 8am daily would fire at 9am while DST is active, and then back to 8am when DST ends? (Assuming it repeats for that long.)
Do you mean that if you schedule something for Jan 6th and then it advances through a leap year, it would fire again on the 5th?
How is this the case and what are the ramifications? It would be good to have more explanation.
