An Hour Behind?
Okay, so I reviewed my flashcards. I expected that now it'll say "just now" on the words I practiced. However, it says "53 minutes ago".
Has anyone else experienced this?
It sounds like you are in a place which uses daylight saving and your clocks have been moved on one hour. Duo is probably still using your original time zone so thinks your time is one hour behind what it is currently set to.
I'm in Scotland so have British Summer Time which is one hour ahead of GMT, What is your timezone?
