 | Well, generally speaking, you'll need to use the command-line function appropriate to the host operating system to get the datetime value as a string, then concatenate that with the string contents of your stderr in order to save the concatenated string as a file. 
 Have you tried going down that path?

 Thanks a lot. I am using echo %DATE% Shell Command-line and concatenating the result to actual step result to add in file.

 When you put it that way it sounds like you already have it working. Is that accurate?
