Early Switch users are discovering certain playtime stats gathered since the console’s launch are resetting and erasing info.
On the Switch, players can go to their profile in the upper left corner on the home menu and look at the last 20 games they have played, along with how many hours were spent in each one. The Switch takes a week to process playtime when a game is first booted, and with that users are noticing the stats are taking the day and month into account, not the year.
For example, if you played Breath of the Wild when it and the console released on March 3, 2017, and the current date is March 4, 2018, the stats will say you played the game one day ago, even if you have not booted the game in months, effectively erasing any recorded time you spent in the game.
Nintendo has yet to say if the issue will be fixed. We have reached out to them and will update the article with any new information.
This is a substantial issue for those who care about tracking the time spent with a game. It might be a small feature in the grand scheme of the console, but that time is a unique way of reminding players of the times they had with a game, for better or worse.
