org-time-today is void   Recently updated !

After I update my org-mode version, org-time-today function has just disappeared.

As awesome coder, I did search in the old versions of org-mode and copied this function from this file to my init! Now everything is perfect!!!

Keep Emacs error in the article! for better search engine indexing.

Give version information to being good coder.

Also share technique lead us to success1.
