Wrong dates on Dashboards and posts tier setup

Ghost-CLI version: 1.21.0
Ghost version: 5.2.3
Selfhosted Ubuntu 20.04

Dashboard has section with “Recent posts” and “Member Activity”.
All dates and time here shows current login date and time.
For example if I login at 6:29 PM in July 10th as admin, then this date and time is displayed.

Another problem.
Adding a post, I choose “Post access” tiers. Saved new post is always available for chosen tiers and “FREE” members (free tier is not choosed). I need to go back to a post, delete one tier, save the post, re-add a tier and save post, then “free” access is gone.
