Hello, I had noticed a bug in October when switching to winter time (but hadn’t planned to track it precisely), and it happened again this weekend when switching to summer time: I have some scenes that use the triggers « At each sunset/sunrise », and they only bug for one day: the Sunday following the night of the time change. Here are the trigger times observed this weekend: - Friday 29/3 : the sunrise trigger activated at 6h21 - Saturday 30/3 : triggered at 6h19 : ok - Sunday 1/4 : triggered at 8h17 : not ok, it’s 1 hour too late, it should have been 7h17 (new time) - Monday 2/4 : triggered at 7h15 : ok, it’s working again And for sunset: - Friday 29/3 : the sunset trigger activated at 19h01 - Saturday 30/3 : triggered at 19h03 : ok - Sunday 1/4 : triggered at 21h04 : not ok, it’s 1 hour too late, it should have been 20h04 (new time) - Monday 2/4 : I suppose it will work again, with a trigger around 20h05… That’s it, I don’t know if it’s possible to fix this… ---

Hello. Yes, the error has already been reported here [Gladys n'est pas passé à l'heure d'hiver - #13 par pierre-gilles](https://community.gladysassistant.com/t/gladys-nest-pas-passe-a-lheure-dhiver/8428/13?u=cicoub13) This comes from the library we use, but they are not fixing it. ---

Ah indeed, I’m late to the party 😉 And since it sorts itself out on the second day, it’s not too bad…
