In the Nick of Time

Sometimes I come across an origin story that makes me shake my head and wonder, "Is this for real?" That was how I felt when reading about the phrase “In the Nick of Time” which has come to mean an action performed just before it is too late. 

It seems to have originated in the 18th century. People kept track of the money they owed to creditors with a stick - a tally The stick was carved with the number of days you had until the loan was due. If you paid before the last nick, then you didn’t owe interest on the debt. You made it in the nick of time.
