No, I mean Time Value of Money.
The time value of money (TVM) assumes the present value of money will grow through investment.

It is basic economic concept.
A simple example:
You deposit $100 into a CD, savings account, etc. In a year, you will have $105. The bank then takes your $100 and loans it to some schmuck for something. They are going to charge that person $10 a year to service the loan.
Thus, the bank immediately 'created' $100 that didn't previously exist and will make $5 in a year as well. You make $5 in a year. So, now there's $200 in the economy. In a year there will be $215.
Gold is an artificial standard. We could as easily use steel, aluminum, or sand as the standard. The problem with any system using a commodity as the basis for how much money there is, is that it creates artificial constraint on the money supply.
The time value of money concept means that wealth grows by investment in the economy. More goods and services means there's more basic money to use and when you can loan invested money out it creates even more wealth. Our current system of economics wouldn't be possible without it. The prior gold standard (or a monetary system based on a commodity) created scarcity. That was a driver for wars over wealth for millennia.
