No although it might look like that.

It's more to point out that the later it gets the more powerfull she becomes, hence the improved scent and hearing. It also kind of makes her abit more aggressive. On the other hand once it's early she will lose alot of her power.

I know that's a shitty explaination so here is a short one: Midday she is at her weakest, midnight she is at her strongest. Her powers and personality swing by the time of day.
