I've checked the patch, and the transition is applied correctly this
September (and contrary what I though, it doesn't affect April's fools… I
mean, April's transition)

On previous occasions, I've shared the first official or press source
available (in this case, the verified Twitter account from Ministerio del
Interior); and then I share the decree from the Official Gazette (the
legally binding document). It was published on Ministerio del Interior site
a few minutes ago:
https://www.interior.gob.cl/noticias/2022/08/09/comunicado-el-proximo-sabado-10-de-septiembre-los-relojes-se-deben-adelantar-una-hora/

Thanks,
Juan
