Now bring your cursor over the text on the bottom right which tells when the poll closes. It shows you that the exact time of closure is 1 pm. No matter where you are and what the local time of your device is. It can be confusing. A very minor issue but maybe worth fixing some day.
I’d say it’s pretty unexpected given that the other dates in the app (hovering over the post date in the top right, or the created / last reply dates in the topic summary, for example), are given in the user’s time zone.
