Only at 4 a.m. on the morning of departure was the STD changed to 9h15:

5 Apr 04:00 Time Adjustment Estimated Gate Departure changed to Apr-05-2020 9:15 AM

That's a delay in my book, and that's how others see it too:




Same holds true for Monday's KL1229, except it was delayed even longer:



No doubt these delays would also technically be considered as such under EU261. KL would never get away with saying "the flight left only two minutes late because we changed the departure time four hours before STD". Heck, by then some pax would already en route to or maybe even at the airport.

For today, Tuesday, a KL1229 record was created last Saturday:

4 Apr 22:13 Record Created Time Adjustment Scheduled Gate Departure changed to Apr-07-2020 8:00 AM Scheduled Gate Arrival changed to Apr-07-2020 9:25 AM

No doubt they will change the STD in a couple of hours.
