Why does the clock say 410 on the one hundred dollar bill?

The clock on the front of the U.S. one hundred dollar bill shows the time as 4:10 to symbolize the founding of the United States as a nation. The number 4 represents the fourth month, April, which is when the Declaration of Independence was adopted. The time can also be interpreted as a nod to the concept of "time" in relation to the nation's history and the importance of liberty and independence.
