date, n. /deɪt/
Similar to their use of figs, merchants in New Testament–era Israel would use the fruit of Phoenix dactylifera (now called the date palm) as a crude form of calendar. Its average rate of spoilage had been carefully observed and recorded, and particularly experienced merchants could tell the time down to the hour with just a glance.
Even they would admit that it was not a perfect system, and disagreements would periodically break out over improper temporal calculations. For this reason, date time was replaced with joda time.
