When we set sail from Gran Canaria sun set around 18:30 and rose around 08:00. As we are now approaching the 32nd longitude we noticed the change where sun set and sun raise are now about an hour later. We take a noon sighting with our sextant which confirms local noon, ie the sun at its zenith overhead is about 14:18 UTC. So we move the clocks back one hour during the day rather than during the night to ease the watch keeping process.
