What does phrase "by which time" in the sentence "She finally called a solicitor, by which time the hotel had been closed down" mean?
I have only learnt that phrases "in which, at which, on which" have the same meaning with "when" and "where" in many cases in relative clause like this: Christmas day, on which almost everyone is happy, falls on December 24th.
I don't know how to use other phrases like "by which time" in relatice clause and I don't understand what they mean. Please tell me how to use a preposition together with "which" in detail.
