Forum Sidebar times are crazy
 

Hi,

since last night I have a very weird thing: the times on the newest posts and threads blocks in the sidebar go crazy. They obviously change time zones at random. The times of the forum itself are correct, only the sidebar blocks change, and it looks like by themselves.

I didn't change anything, no new addons or anything! I checked the suspect files, everything is OK. Have you ever heard of such a thing? What could be the reason for this strange (spooky...) behavior and how can I fix it?

I am currently running 4.0.7 on my live site.

Thanks!
