But, it only remains a hint and nothing clear is stated:

Although one cannot provide as clear a date as one can with the example you mentioned, still it seems that Gandalf visited Angmar, as I mentioned above in the quote. I guess this could have been in the Third Millennium, but I don't really see why he would have done so after Angmar was no longer a threat.

Also not discussed as much is the quote about Gandalf going in very guises. This suggests to me that he did not always venture forth as Gandalf himself, which might also explain the lack of records on him in the Second Millennium...
