[Norse Mythology] In what time period was Thor born?

Let’s accept the standard presentation of Norse Mythology as true. 

Ymir the giant came into being in the early days of creation. In time, the first Aesir god emerged from the ice. Eventually, his descendent, Odin, kills Ymir. Odin becomes the king god. He then fathers Thor, who goes on to be the hero of legend that we all know and love. 

So, in what time period was Thor born? How old is he?

It's not actually stated, and Thor might be a god from an older religion's pantheon, as he's sometimes referred to as "Old Thor" despite being presented as an adult man in his prime in all aspects of the deity.
