A man in a church where I served an interim pastorate was a retired police officer who had worked the evening shift. He said that one of his jobs was to make sure the police department clocks were all in sync with one another and with the clocks at City Hall. Each evening he called City Hall to get the time from their clock. It was years before he learned that each morning City Hall called the Police Department to get the time from their clock. They just kept recycling the same time, right or not.
Children of God, be careful where you check for the time, redeeming the time, because the days are evil. Ephesians 5:15-16. [Okay, the Greek is a little fuzzy there.]
