Are these Dummy subjects?
It was nice to see him
It's obvious that in this sentence "It" is a dummy subject and the sentence can be reconstructed as "To see him was nice".
But what about this: It is time to watch
Is the case same here as in the first one? Can it be reconstructed to "To watch is time"?
Also wanna ask something additional: We were happy to see each other Now what happens in this sentence? "to see" is something lie a complement to the adjective "happy"?
Some other examples like this one: He is ready to play, She is prepared to play the piano
