Keyword researching, time of day?

I've been trying to target what time of day people are searching for my keywords, with less trial and error via Adwords.

I was wondering if anyone has ever heard of a KW researcher that follows what time of day it's most being searched.

I'm pretty new to this but this would help me a lot.

 

Any idea? Is it really even possible?

 

Nope , but you could take note what time of the day you get the most clicks
