I'm looking to create a type of puzzle that involves the passage of time where the puzzle can only be solved a specific times / days in a year. It could use environmental surroundings like the sun/ weather/seasons/stars/etc. Or it can be linked to something "virtual" that resides on the internet. Has there been any type of puzzles that used these elements?

This scene from Indiana jones springs to mind. The puzzle can only be solved at a certain time of day when the light is shining through the hole and you have the special staff. Here's a link to the wiki page
