I am trying to do the same thing. I change the timestamp in mongoDB, but it has no effect on the frontend.
Ps.: I changed the timestamp on topic, post and topics:recent.
Anyone can help me?
My page has changed design by itself and the recent messages are not displaying - any help greatly appreciated. Cheers Rod
Looks like you had the "Cyborg" theme selected. You can change the theme in the admin control panel, and then restart your NodeBB to see the changes
thanks very much
