The StudyTiming element defines a timing constraint within the study, which can be an absolute timing constraint (e.g., start of the screening visit must be between 1 January 2022 and 31 December 2022), a relative timing constraint (e.g., visit 2 must be within 30 days after visit 1 with a window of +/- 1 week), a transition timing constraint (i.e., timing constraint on a transition within a defined workflow), or a duration timing constraint (e.g., the duration of visit 2 is planned to take hours with a window of 30 minutes).
