Hi:

Basically, you need the INPUT function to convert your character string into a DATE/TIME variable that represents the number of seconds since midnight Jan 1, 1960. Then, once you have that number, you want to extract the date only using the DATEPART function and extract the time only using the TIMEPART function. The INPUT function needs to know how to convert your value from a character to numeric variable, so it can use the ANYDTDTM informat in order to do the conversion. A model program and the output (in the SAS Log) is shown below.

97 data convert;

98 charvar = '2011-01-01-08.35.26';

99 numdt = input(charvar,anydtdtm.);

100 date = datepart(numdt);

101 time = timepart(numdt);

102 put charvar= numdt= date= mmddyy10. time= time8.;

103 run;

charvar=2011-01-01-08.35.26 numdt=1609490126 date=01/01/2011 time=8:35:26

NOTE: The data set WORK.CONVERT has 1 observations and 4 variables.

Hi,

Great code from Cynthia, the only thing I can add is if you still want the date formatted with dashes yyyy-mm-dd you can use yymmddd10.. The third d scpecifies the dashes.
