I like this one! Just tried in in o3, it generated 10:10 3 times. Then it got frustrated and wrote a python program to do it correctly. Then I passed that image into o4 and got a realistic looking one... That still showed 10:10.

Search for 'clock' on Google Images though and you'll instantly see why it only seems to know 10:10. I'll keep trying this one in the future, since it really shows the influence of training data on current models.
