You’re referring to Unix time, which is generally acceptable (if too small). The GP I think is referring to the art of storing Jan 1, 1970 8:11 as the number 19

You’re referring to Unix time, which is generally acceptable (if too small). The GP I think is referring to the art of storing Jan 1, 1970 8:11 as the number 197001010811 —- YYDDMMhhmm format, but as a number rather than a string. Which isn’t really that bad, since it’s ultimately the same as problem as Unix time, but it’s definitely an unnecessarily abusive encoding that’s distinctly worse than Unix time for no real gain
