Time in game off by an hour on Steam Deck

I’ve noticed that when playing the new Season on my Steam Deck the time is ahead one hour. The time is correct on my Steam Deck, in D4 it’s an hour ahead. I’m in AZ and on MST, which due to daylight savings is currently the same as PDT so I imagine this is something to do with daylight savings?

I’m not seeing this issue in the Battle.net version on my Windows PC.
