Most people occasionally pause to look up at the moon, but have you ever pondered what time it is up there?
Those who have may soon have an answer to their query since space organisations are thinking of giving the moon its very own time zone.
The European Space Agency (ESA) has stated that dozens of lunar missions, including those to construct bases and other habitats on the moon, are planned for the following ten years.
At the ESA's ESTEC technological centre in the Netherlands, negotiations concerning lunar timekeeping started in November 2022.
Pietro Giordano, an engineer for the ESA's navigation system, stated: "We agreed on the significance and necessity of defining a standard lunar reference time, which is recognised globally and to which all lunar systems and users may refer.
"A coordinated multinational effort is currently underway to accomplish this."
Up until this point, each new lunar mission has functioned on its own schedule, using deep space antennae to maintain the onboard chronometers in sync with Earth time.
Any infrastructure that is created and run on the moon would require exact synchronisation and timing, much like GPS systems on Earth do.

After November 2024, NASA's Gateway station will start operations as a multi-purpose facility circling the moon.
It will be accessible to astronaut stays and offer assistance so that people may go back to the moon's surface.
The ESA will be deploying its own Argonaut lander on the moon in the meanwhile.
Not only will these missions be active at the same time on or near the moon, but they will also interact, perhaps transmit messages, and conduct cooperative observations.
According to the ESA, the worldwide team working on the matter will encounter "significant technological hurdles."
Why do clocks on the moon managed separately?
The moon's rotational period is 28 days, which is different from the 24-hour day we experience on Earth. This means that a day on the moon would be longer than a day on Earth. If the moon were to have its own time zone, the clocks would need to be adjusted to keep track of the moon's unique day. In order to keep track of time on the moon, any clock would need to be able to count 28 days. This is difficult, as most clocks are designed to count days that last 24 hours. To accommodate this, scientists would have to develop a new type of clock that would be able to count 28 days, or even longer. This new clock would need to be able to adjust its speed in order to keep track of the moon's rotational period. The moon's orbit around Earth is also slightly elliptical, meaning that its speed changes slightly as it moves around our planet. This means that any clock designed to keep track of time on the moon would also need to be able to adjust its speed based on the moon's changing orbital velocity. If the moon were to have its own time zone, this new clock would need to be used to set official time for the moon. Every 28 days, the clock would need to be reset to ensure that it was keeping track of the moon's unique day. This would be a difficult task, as the moon's day is longer than Earth's, meaning that the clock would need to be adjusted to keep up. Of course, all of this is purely theoretical, as the moon does not currently have its own time zone. But if it did, scientists would need to develop a new type of clock that could keep track of the moon's unique rotational period and orbital velocity.
While clocks tick slower in greater gravitational fields, clocks on the moon run faster than their equivalents on Earth, adding about 56 microseconds or millionths of a second every day.Their precise pace varies depending on where they are on the moon, ticking more quickly on the surface than in orbit.
Of course, the accepted time system will also have to be practical for astronauts, according to Bernhard Hufenbach, a member of the Moonlight Management Team from the Directorate of Human and Robotic Exploration at the European Space Agency.But now that we have a workable time system for the moon, we can apply it to other planetary locations.
