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:
Yes you are correct, segments will disqualify at the beginning of each day so hours and seconds are ignored. If you have recency of 1 day, and you make the event at 11pm, you'd effectively disqualify about an hour later.
It would definitely be a nice improvement to include a particular time of day, I'd suggest you post this in the 'Ideas' section of the forum.
