HL7-defined code system of concepts specifying the degree of precision of the time stamp (Y = year, L = month, D = day, H = hour, M = minute, S = second). Used in HL7 Version 2 messaging in the TS datatype. Note deprecated in 2.5.1 and retained only for backward compatibility, as the datatypes and architecture for the degree of precision for timestamps was changed.
