Timing variables not directly characterizing AVAL (e.g., *DT) should be prefixed by a character string instead of the placeholder asterisk shown in Table 3.3.3.3, so that their actual names comply with the variable naming conventions described in General Variable Conventions. In many cases, the prefix for these date and time variables would match that of an SDTM --DTC, --STDTC or --ENDTC variable name. For example, if a numeric date variable were created from --STDTC, then it would be named --SDT. However, if --DTC or --STDTC is the date that is associated with AVAL and AVALC, its numeric equivalent should be named ADT or ASTDT, as appropriate. The timing variable conventions documented in Timing Variable Conventions, apply here as well.
