if i sync early on in the day (Perhaps before its officially the next day in GMT?) i get the correct date, it seems to be days i wait until late like today to fetch the news it shows up as the day after. (Late being like 8pm)
I noticed this as well when i attempt to remove the books from today:

the image is a screenshot showing the "date" of the removals and conky in the bottom left shows the current time and date.
