IEEE data source issue: "P1680" has wrong dates for drafts

[ronaldtse]

Publication dates shown in the IEEE official data source can be unreliable:

https://ieeexplore.ieee.org/document/5325044

All these drafts can't be published on the same day (Jan 1, 2009). This is clearly a mistake in entering the publication dates of these drafts.

In addition, the draft sequence doesn't even fit with the dates given in the PubIDs.

• D2: undated
• D3: PubID says Aug 2009
• D4: PubID says Jan 2009
• D4D6: PubID says Aug 2009
• D5: PubID Jun 2009

Not sure how this can be possible.

I also suspect that D4D6 is a diff between an unpublished D6 against D4.
