On the last 18th, some users reported the wrong time change to keep up with the calendar used until 2017, which started daylight saving time on the third Sunday in October. In 2018, the start of daylight saving time was postponed to the first Sunday of November – until canceled by President Jair Bolsonaro in 2019.

According to Google, the various modifications have a direct impact on the IANA Global Database (in Portuguese, Internet Number Assignment Authority).

In practice, this means that some cell phones may not have the information necessary to prevent the watch from being automatically updated at the time and day scheduled to begin daylight saving time 2020, which has been canceled by the government. That is, at midnight this Sunday, November 1st.


Also according to the company, the risks are mainly for those who have a cell phone with a version of the system prior to Android 10, which does not have a feature that facilitates the updating of the IANA database. Last year, Chromecast and Nest Hub devices also suffered from automatic switching.
