Room deletion progress shows timestamp in the future

**Describe the bug**

I think the room deletion was triggered automatically by the Synapse configuration (forgotten room).

It shows a "since" timestamp 2 days in the future. See screenshot below.

Both my server and client clocks are running correctly and use the correct timezones.

**To Reproduce**

In my case: Login, view forgotten room. But I doubt it can be reproduced that easily.

**Expected behavior**

Show a timestamp that is closely below the actual time.
