Adding timezones into

your Upcoming feedMatt Harris

1

ProblemUpcoming doesn’t know about timezones

Their events are “floating”

Different timezone events show as the same timezone in your calendar

2

Solution

Add a timezone to the event ... but how?

3

What do we have?Start date, end date, start time, end time

problem: their floating times

longitude/latitudeBad, not actually used

Country code Good, but what about multi-timezone countries

City OK, but it was entered as free text
