TAETORD Planned Order of Element within Arm Num Timing Number that gives the planned order of the Element within the Arm for the Element in which the medication administration started. Null for medications that started before study participation. Perm
EPOCH Epoch Char Timing Epoch associated with the start date/time of the medication administration. Null for medications that started before study participation. Perm
CMSTDTC Start Date/Time of Medication Char Timing Start date/time of the medication administration represented in ISO 8601 character format. Perm
