The clock: Port-Gentil keeps UTC+1 almost exactly on the equator.
Port-Gentil lies at 8.8°E. Its time zone, UTC+1, is built around the 15°E meridian. The 6.2° gap between them means the clock runs roughly 25 minutes ahead of the sun: solar noon arrives at about 12:25 rather than 12:00. The zone holds UTC+1 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 12h 10m of daylight. The shortest is 22 June, with 12h 5m. The swing between them is 5 minutes. Within a few degrees of the equator the length of the day barely moves all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Port-Gentil the sun comes up earliest on 3 November at 06:04, while the latest sunset waits until 12 February at 18:43. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Port-Gentil that civil twilight runs about 21 minutes at the equinox.
