Using pytz Olsen timezones rather than just defining the offsets ourselves is incredibly useful.
One of the reasons for this is that timezones for a given location can change.
For example, if we’re in Germany we have 2 timezones, thanks to daylight savings time:
- Central European Time (CET, UTC+0100)
- Central European Summer Time (CEST, UTC+0200)
Let’s see this in action, let’s take the same local time in the winter and in the summer and see what happens.
