Timezone issues - Githubissues

rnovacek commented 11 months ago

There are some problems if the current timezone is different than Europe/Prague.

For example with London timezone, this error occurs:

                  ~~~~~^^^^^^^^^^^^^^^^
KeyError: datetime.datetime(2023, 7, 11, 23, 0, tzinfo=datetime.timezone.utc)

Workaround is to set the timezone to Europe/Prague.
