I'm not sure if this is exactly what Heidegger had in mind when he rethought the relationship between Being and Time, but this story strikes me as an interesting example of the relationship between the two.

Alex Rodriguez hit is 499th career home run Wednesday night. However, today he will play in a game that actually began on June 28. That is, the game was suspended in the middle because of weather. If A-Rod hits a home run in that resumed game, then home run 499 magically becomes home run 500:

On Friday, A-Rod will be on deck when the Yankees resume a suspended game against the Orioles in the eighth inning. If he homers in the completion of the suspended game, it would count as being hit on June 28, when the game began. That would make it home run No. 493 -- and Wednesday night's would become No. 500.

The rule, 10.23 (d), states: "All performances in the completion of a suspended game shall be considered as occurring on the original date of the game."
