Having said that, you will have some serious issues is your dates are
generated from around the world and not purely in your local timezone.
A lack of timezone (Europe/London, Europe/Berlin) rather than the
timezone offset (+1:00, etc.) is the issue here.
Due to DST changes not being consistent worldwide, with the timezones
changing over time, etc. All quite complicated.
