Imputing ISO8601 Dates From Character Variables …
Paper FC06 Imputing ISO8601 Dates From Character Variables Containing Partial Dates John R. Gerlach, MaxisIT Abstract Assume that there is an initiative to include legacy studies into a database such that the original data are converted into SDTM domains in compliance with CDISC standards. One aspect of this effort involves date Variables that must follow ISO8601 rules. This sub-task would be easy if the data were stored in SAS data sets and, specifically, the Dates were stored as SAS date Variables . Unfortunately, the plethora of data is stored mostly as raw text files. Moreover, Dates are stored as Character Variables in various formats ( , mmddyyyy, yyyymmdd).
