My understanding is that Chile Continental time changed back to standard time on April 6. See https://www.horaoficial.cl/aviso/informacion.html <https://www.horaoficial.cl/aviso/informacion.html> which states: “Dispone fecha cambio huso horario para el 6 de abril de 2019, de acuerdo a lo siguiente:

That change was added in the TZ 2018f version released 6 months ago and is currently active.

You may check if your system has a good TZDB with something like this:

$ zdump -v /usr/share/zoneinfo/America/Santiago  | grep 2019
/usr/share/zoneinfo/America/Santiago  Sun Apr  7 02:59:59 2019 UTC = Sat Apr  6 23:59:59 2019 -03 isdst=1
/usr/share/zoneinfo/America/Santiago  Sun Apr  7 03:00:00 2019 UTC = Sat Apr  6 23:00:00 2019 -04 isdst=0
/usr/share/zoneinfo/America/Santiago  Sun Sep  8 03:59:59 2019 UTC = Sat Sep  7 23:59:59 2019 -04 isdst=0
/usr/share/zoneinfo/America/Santiago  Sun Sep  8 04:00:00 2019 UTC = Sun Sep  8 01:00:00 2019 -03 isdst=1
