After spending a few days in Jordan I found out about the reason for the mysterious 1 hour schedule change notified a few weeks ago by TK, LH, OS etc (I guess all airlines flying to Jordan).

The Jordanian government decided on 5 Oct. that Jordan would keep daylight savings time/summer time, i.e. not adjust the time 1 hour on 28 Oct. 2022 (like European/neighbouring countries).
Results: from 28 Oct. flights would arrive and depart 1 hour later than originally scheduled by the airlines; hence the scheduled chance/retimed flights notified to pax (which worked out great for me as it allowed me to (invol) change my flights into much more expensive travel dates).
