By default, timestamps are in the GMT time zone!

Timestamps are accepted in the GMT time zone. That means that your annotation may not be plotted where you would expect it if you do not provide a full timestamp. For example, '2020-01-02' may be plotted on '2020-01-01' if you are viewing data from the eastern time zone. Because of this, we suggest users to provide full timestamp whenever possible.
