Admit DtTm is not as simple of a concept as it might seem, and it's definition and storage in our database has changed over time. This page gives some definitions and how we have implemented them.
If Visit Admit DtTm > #2020-10-15# then earliest Service tmp entry DtTm in profile else if available, Accept DtTm, else if Arrive DtTm
Service tmp entry is not yet part of Minimal Data Set; I have flagged on that page how it needs to be included; will need to be considered as part of Change to replace Accept DtTm with first Service tmp entry, and Arrive DtTm with first Boarding Loc.
