Nope! The Aramaic word does mot mean years but appointed times of periods of time or a set definite if unspecified period of time. You should check the Lexica materials.
The mention of Gid's Kingdom/rulership is thematic in not only ch.4 but the entire book of Daniel so it plays a major role in the interpretation of the tree dream.
No , the connection between both period is grounded within the test such as the OG translation of Dan.4 which makes the connection explicit.
