(adsbygoogle = window.adsbygoogle || []).push({}); In another thread i posted that the clock might have something to do with the arrival of the Hell Hounds. it would at least give you a little warning.
It also could mean when the WunderWaffle leaves according to some people.
On another site someone hinted that it signals the arrival of the giant that they hinted about in the radio messages. On another thread i posted i talked about the new look for the zombies, could this signal when they change their appearance and when they get much stronger.

The stop watch in the top left corner is the time you have to link the tekeporters. But the giant clock on the building is something i dont know. But the clock is always say 1:15. If anyone remembers from shi no numa element 115 was used to power the wonder waffe, made the dogs, and came from the meteor outside the storage room.

the small clock is definitely the tele time but the big clock is prob nothing other then an easter egg like ninja said

ya its probably just there for decoration lmao

They would not add it just for show it has to mean something
