Currently listening to French broadcast on 9435 AM (rough copy but legible enough). It began at 1600 when it was previously scheduled for 1630. (Although North Korea moved forward by half an hour, from UTC+8.5 to UTC+9, the effect on the broadcasts is that they now start half an hour earlier.) I wasn't listening in earlier because their signals haven't been good this morning, but I'm guessing that they made the change either at 1500 UTC, when Korean Standard time was at midnight May 5th, or at 1530 when the Pyongyang time zone hit that mark.
A few days ago North Korea Tech speculated that the thawing relations between North and South would lead to and end, or at least a detente, on the radio wars front. To that end, it will be interesting to see which clandestines are still on the air the next time I can copy them (in my QTH, that's generally 1000-1400).
