This is the closest I have found, but the FDS is still not responsible as I read it:

If we remain faithful, God will not let us make ruinous mistakes. But sometimes he permits us to be in error so that we may see our need to look always to him and his Word. This strengthens our relationship with him and our endurance while waiting. We learn from our mistakes that it is necessary to be more careful in the future. The desire for the new system of things to take complete charge of the earth has always been very strong in Christians down through the centuries. And because of their own short life-span, they doubtless longed for it to come in their particular lifetime. Those who have tried to keep God’s judgment time “close in mind” have, on more than one occasion throughout history, become overly eager for that day’s arrival, in their own minds trying to rush the arrival of the desired events. (2 Pet. 3:12) In the first century, for example, the apostle Paul found it necessary to write to Christians in Thessalonica in this fashion, as we read at 2 Thessalonians 2:1-3: “However, brothers, respecting the presence of our Lord Jesus Christ and our being gathered together to him, we request of you not to be quickly shaken from your reason nor to be excited either through an inspired expression or through a verbal message or through a letter as though from us, to the effect that the day of Jehovah is here. Let no one seduce you in any manner, because it will not come unless the apostasy comes first and the man of lawlessness gets revealed, the son of destruction.”
In modern times such eagerness, commendable in itself, has led to attempts at setting dates for the desired liberation from the suffering and troubles that are the lot of persons throughout the earth. With the appearance of the book Life Everlasting—in Freedom of the Sons of God, and its comments as to how appropriate it would be for the millennial reign of Christ to parallel the seventh millennium of man’s existence, considerable expectation was aroused regarding the year 1975. There were statements made then, and thereafter, stressing that this was only a possibility. Unfortunately, however, along with such cautionary information, there were other statements published that implied that such realization of hopes by that year was more of a probability than a mere possibility. It is to be regretted that these latter statements apparently overshadowed the cautionary ones and contributed to a buildup of the expectation already initiated.
In its issue of July 15, 1976, TheWatchtower, commenting on the inadvisability of setting our sights on a certain date, stated: “If anyone has been disappointed through not following this line of thought, he should now concentrate on adjusting his viewpoint, seeing that it was not the word of God that failed or deceived him and brought disappointment, but that his own understanding was based on wrong premises.” In saying “anyone,” TheWatchtower included all disappointed ones of Jehovah’s Witnesses, hence including persons having to do with the publication of the information that contributed to the buildup of hopes centered on that date.
