That must be right, because 9/11 happened when Clinton was president: so, 2002-2010.
UPDATED: Mea culpa. NMC actually bothers to look up the rule on how these inscriptions are formulated:
The cornerstone should be a cut stone block having a smooth face of size adequate to present the following incised letters: UNITED STATES OF AMERICA, (PRESIDENT’S NAME), PRESIDENT, GENERAL SERVICES ADMINISTRATION, (ADMINISTRATOR’S NAME), ADMINISTRATOR, (YEAR OF PROJECT COMPLETION). The words, UNITED STATES OF AMERICA, should be in letters 50 mm (2 inches) high and other letters should be proportionally sized by rank.Agree with NMC that this is "a silly rule." The confusion to future archaeologists alone militates against it. And really, what's wrong with having the names of both presidents on there -- in office during "development" as well as at "completion"? So the heads to roll should be those of the GSA twerps who concocted this rule.
All names should be of those individuals in office during project development prior to construction, if construction is completed during a subsequent President’s term of office.
