24733 - Use SAS® date and time variables to create a SAS datetime value

Sample 24733: Use SAS® date and time variables to create a SAS datetime value

In the first step, date and time values are read into a SAS data set with the appropriate informats. In the next step, the DHMS function combines the date and time to create a SAS datetime value. The DHMS function contains four arguments: days, hours, minutes, and seconds. Since a SAS date is stored as the number of days since January 1, 1960, this variable belongs in the first argument, 0 values are inserted for the next two arguments, and the SAS time is stored as seconds since midnight so this belongs as the fourth argument.

  format sasdatetime datetime22.;
