How to change the time on a Toyota Yaris

In this video we see how to change the time on a Toyota Yaris, specifically when it comes to switching from daylight saving time to standard time and vice versa. We go to the multifunction screen and press "settings": from there we go to press the clock, simply click on daylight saving time, and the clock will change the time for us, without doing anything else. All we want to do is just adjust the time format to 12 or 24 hours, as is customary in the area where we live: for example in Anglo-Saxon countries it is common to set the time to 12 hours, while in the European Union it is normally set to 24 hours.
