Time is not only out of sync inside containers.
When I build an image with docker having been started yesterday (and my laptop being suspended over night) the output of docker images tells me the image has been created 16 hours ago, even though I created it just a minute ago.
When I try to push such an image to AWS elastic container registry, there is extremely slow transmission speed.
As others already mentioned restarting docker through the tray icon resolves these issues.
Right now I need to restart docker every morning.
