Timezones do nothing but create confusion and make it harder to connect with people in other timezones, instead, we should switch to a single time.
Hear me out, all you have to do is set your clock to greenwich (+0h) timezone and shift your daily activities accordingly, instead of the sun rising at 5 it might do so at 14 for you and that's fine because you went to bed at 7 instead of 22, all you have to do is change the numbers nothing else about your daily life will change, but you will never have to check for timezones again.
