So you prefer to answer the explicit question, not the implied one.
"Do you know what time it is?"
"Yes."
Had a boy call my daughter at home once.
He said, "hello, is <daughter> there?
I said, "Yes" and hung up the phone.
Wife and daughter gave me grief over that.
For all future calls, he said, "Hello, this is <boy>, may I please speak to <daughter>?
I win.
