Does the DB site/app show German time or my regional time?

The DB site/app aren't clear on which timezone their information on trains is in when booking tickets.

I'm trying to prepare and understand so I can book easier later in the year, but I still can't figure out whether or not the times stated are in the German timezone, or my local timezone (I'm from the UK).

I've tried searching the sub's FAQ and Wiki, and just online in general, but I can't find a solid answer. Maybe I've missed something?

I have an account with DB, and my address is on there, but nothing seems to change regardless of whether I'm logged in or not.

A little advice would be appreciated! Thank you! 💕
