Brief description of the issue:   original value 22Feb2018:22:04:01.485 is changed to 22Feb2018:22:04:01.430 when sas dataset is exported as .xlsx using ODS excel and Proc Report combination.   The last 3 digits are changing automatically in the excel export. This happens with proc export with dbms=xlsx. But dbms=csv output seems to maintain the values correctly.   I have tried other formats but they do not work. ODS excel is fine otherwise for all formats.   Seems like this needs to be addressed within SAS software per my knowledge.   Appreciate any feedback and discussions.   Kind Regards.   Addl Information/Steps: 1. Here is the code: ods listing close; options nobyline nolabel; ods escapechar='^'; ods excel file = "&&xlout.&&mem&i...xlsx" style = pearl options (sheet_interval="none" sheet_name="Data"); proc report split='~' nocenter missing list; column _all_; run; ods excel close; ods listing;   2. Here are the original data set values   3. Here is the incorrect .xlsx file output   4. Here is an image of .csv output   5. The define statement from log file is as below.
