Wait, those were grouping parentheses, not application ones. According to https://en.wikipedia.org/wiki/History_of_the_function_concept something explicit resembling modern ideas of a "function" appeared in the 17th century, so THAT's when time began.
I always wondered.
I was referring to grouping parentheses. Most uses of "$" are for stupid things like "sin $ 1 + 2" where parentheses would be much more clear. By "beginning of time" I thought it was clear I meant "I don't feel like looking it up," but thanks -- we now know that people have been using parentheses about 400 years longer than "$" for grouping.
