Using timestamp/time constraint of "yesterday" - what is the defintion?

[HannahCa2]

Hello,

I recently built a campaign where instead of using a 24 hour window, I decided to use the time constraint option of "yesterday" to minimize any overlap in audience evaluation. Can someone confirm what exactly the definition of "yesterday" entails? For example, I am not sure if it is midnight to midnight UTC time, or what? There is not any documentation online that I can find to answer this question. I am using the platform  timestamp of an event.

Thanks

I had a similar question recently (https://experienceleaguecommunities.adobe.com/t5/adobe-experience-platform/audience-evaluation-is-st...). It would be "yesterday" UTC time midnight to midnight (12:00AM - 11:59PM).
