Recency on frequency set to < 1 day, does it mean 24 hours or that particular GMT date?

I was curious to know how the recency period is evaluated in Segments. If there is a rule based trait being used in a segment, that has a recency setting as <= 1 (within 1 day) and frequency set as => 1 (1 or more times). If a user realizes for the trait at 7:00 PM GMT on day 1, does that user fall out of trait on day 2 at 7:00 PM GMT or will that user fall out of trait after 11:59 PM on day 1? 

According to following forum thread it should be former i.e. 24 hours:

But, there is nothing I could find in user guide: https://docs.adobe.com/content/help/en/audience-manager/user-guide/features/segments/recency-and-frequency.html
