Edge browser was launched tomorrow

At 6:20 pm on 9/14/18, I received a message from Norton that said,

"Microsoft Edge browser launched

Hi [name],

[Name] used the Microsoft Edge browser today, 9/15/18."

I'm wondering how [name] used the browser tomorrow. 

Hi mb7

Could you please check if there is any difference in timezone settings between Norton Family web portal and your child's PC.
