Hello everyone, Sorry for the delay, I would like to thank everyone for your time and your attention to my problem and the comments and solutions you provided. I really appreciate your kind help. Regards, @Kurt_Bremser I strongly agree with the idea that using two digits for indicating the year value is not clear and appropriate. The problem is that the data I'm talking about is part of a set of an API log files that I don't produce but I can only read them to extract some data for doing statistics. Unfortunately I don't have neither access to the source code nor the power to impose this best practice rule. Thanks a lot for your help and your comment. Indeed by concatenation you suggested, standard formats based on SAS documentation can be used: http://support.sas.com/documentation/cdl/en/lrdict/64316/HTML/default/viewer.htm#a003169814.htm Thanks a lot.
