What is the name of the time-traveling Ice Age short film released in 2006?

The 2006 time-traveling Ice Age short film is titled No Time for Nuts.

The short centers on Scrat and an acorn-related encounter with a time machine. His attempts to use the machine send him across different eras, where he repeatedly tries to recover his prized acorn while causing increasingly elaborate chaos.

No Time for Nuts was released as an Ice Age short rather than as a theatrical feature. It was created by Blue Sky Studios and became notable for extending Scrat’s familiar physical comedy into a science-fiction premise involving time travel.

The title is sometimes confused with Gone Nutty, another Scrat-focused short, or with the later Scrat’s Continental Crack-Up shorts. Those productions also feature Scrat, but No Time for Nuts is the one built around the time machine.
