Elon Musk, despite his dramatic drop in popularity, is still planning his Mars mission. A critical factor surely would be to easily keep track of time under these conditions. Clocks could be adjusted to account for different gravitational time zones, just like we adjust them for different geographic time zones. In fact, something similar is already being done with GPS satellites, which experience both gravitational time dilation (because they are farther from Earth's gravity well) and velocity-based time dilation (because they move relative to the Earth). The onboard clocks are intentionally adjusted to compensate for these effects.
If this idea were to be extended systematically across the solar system, we could establish gravitational time zones based on the strength of local gravity. For example:
"Earth Standard Time" (EST) could be a baseline, with all other times adjusted relative to it.
"Moon Time" (MT) would run slightly faster than Earth time because the Moon’s gravity is weaker.
"Jupiter Time" (JT) would run slower than Earth time due to Jupiter’s strong gravity.
"Mars Time" (MT) would be slightly different from Earth time but much closer than Jupiter’s.
The issue is that gravitational time dilation is not a fixed, stepwise difference like terrestrial time zones, which are based on Earth’s rotation. Instead, it's a continuous effect that depends on altitude and gravity and where applicable speed. A more practical approach might be to define a standard gravitational reference frame, say "Earth Time," and then compute the local time adjustments dynamically for each location.
This could be incredibly useful for precise scientific measurements, deep-space missions, and future interplanetary commerce. A "Universal Gravitational Time Correction" (UGTC) could be applied to clocks, allowing them to function correctly anywhere in the solar system.
