Hiya @hd_steve !
You can change the user's locale and the date format should change in the FusionAuth administrative user interface. More details here: https://fusionauth.io/community/forum/topic/718/how-do-i-change-the-localisation-timezone-for-the-fusionauth-ui?_=1614788141466
Let me know if that answers your question, please.
Thanks,
Dan
