Im still waiting for your answer.
Someone asked Jesus about 'time' once.
What was His reply?
Mark 13:32
"But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.
WHY would the Father even NEED to know the time; you ask?
My question was whether or not heaven was on the 24-hour clock. As for your quote, I think Mark was referring to the time of a specific occurrence or event (i.e., only God knows when something will occur or happen), and NOT about the measurement of time in heaven.
