What exactly is considered to be a timestamp?
Does it have standard formats? Is it language specific? How does it work?

A timestamp is basically a numeric value of seconds, between 1st January 1970, to January 19, 2038 (aprox.). That is simply because the integer is "maxed out" at 2147483648 seconds. You can read more about it here.
As for the format, a lot of languages ( I assume all, but am not sure) allow you to set your own format, like dd/mm/yyyy, mm/dd/yyyy etc.
Here's an example in PHP. This gets the current date, and outputs it in your desired format.
$date=date("Y/m/d");
echo $date;
The output will be 2019/11/20
Not every language is the same tho, so this may vary from language to language. Hope it helps!
