At the moment no. All the stats are running on GMT which isn’t ideal. We need to update this but it’s quite a tricky thing to do. Stat change over times (midnight) would be different for everyone and then we need network wide stats as well. I’ll put it on the todo list for the next update. To just change it in the recent self-mining payments section would actually be quite simple, we could just adjust the timestamp client side but I think that might cause more confusion as people will see they have x in todays earnings but this doesn’t correspond to the recent self-mining payments.
Anyway I’m turning this into a dev conversation. Short answer is no but we know it’s an issue and hopefully will get it improved in the next update.
