Ihor,

  * In an org buffer, input: [1960-10-16]
  * Set point between the brackets.
  * Press C-c ! and enter.
  * The result is [19_*7*_0-10-16 Fri]
  * I expected [1060-10-16-Sun]

Yes, C-c C-c works.

But C-c ! enter is supposed to use [1960-10-16] as the default date and 
not change that date to 1970.


(Yes, I am replying to the correct thread which corresponds to the bug 
report submitted.)
