A native Anglophone lady is showing around her house on TV. When they walk into a room, there is a big clock on the wall, and she points at the clock and says:
"That is not the time."
I understand that the clock has run out of the battery (she also says this), so the clock is not showing the correct time.
However, I would never be able to make up such a sentence as a non-native speaker. I would probably say ""The clock is not correct.".
So, I searched for the sentence on google, whether it is common to mean the clock is not working, but I could not find any. So, I am kind of surprised.
Also, the sentence "That is not the time" reminds me a meaning such as "It is not the time to play/to eat/to drink/to sleep etc" which is used to warn someone not to do whatever it is they are doing at the wrong time or place.
So, is the sentence "That is not the time" an idiomatic way of saying that a clock is not showing the correct time?
Here is the link. She says the sentence at on 3:10
