Check the specification of Animation time in Material Graph

I recently found a node called “Animation time” in the Material Graph.
“Animation time in seconds from the start of the animation.” was the description, so I thought I could use it in my project and checked the behavior.

However, it moves back to 0 after about 4.17 seconds have passed.
Since I want to use it as a counter, I would like the number of elapsed seconds not to return to zero.

Omniverse Create 2021.3.6

This is an addendum to the information.
Seconds linked to timeline?

I’m sorry! It’s resolved.
Simply, I was able to get the number of seconds during animation from the Material Graph’s Animation time.

I was also able to get consistency.
