Broadly speaking, when a point moves with respect to a coordinate system, the line or segment or curve formed by its motion is one of the time of the point at rest with respect to the coordinate system. Each point corresponds to multiple times. Relative to a certain time, the stationary point starts moving faster and the time is slower. When the speed is the same as the moving point in the time, the time stops. When the speed exceeds the point, it is equivalent to going back to the past.
That's real time, real time. Refers to the time taken when a point does not move in the extra dimension.
That's imaginary time, imaginary time. Refers to the time taken to move in the extra dimension.
Relation with space
Space makes things have changeability, that is, because of the existence of space, things can change. Space is a thing without energy, that is, when things can be changed, the energy generated by the change has cancelled out with the energy of obstruction.  the description of the point changes in space is called the described point corresponds to the time of the point [when the point moves to a certain position, the described point will have a unique corresponding position, which is called the position of the described point at this time].
The position of the described point can change with time and remain unchanged. It can be known that time has a functional relationship with the position of the described point.
Gravity, on the other hand, is a universal force between all forms of energy or mass. It can't be confined to the membrane, instead, it has to permeate the entire space. Because gravity can not only dissipate, but also spread out into extra dimensions, it should decay more with distance than with electricity. The electricity is confined to the membrane. However, we know from observations of the orbits of the planets that the gravitational pull of the sun decreases as the planet moves away from the sun, in the same way that electricity decreases with distance.
So, if we do live on a membrane, there must be some reason why gravity doesn't spread out from the membrane very far away, but is confined to its vicinity. One possibility is that the extra dimensions end up on a second shadow membrane, not far from the one we live in. We can't see this shadow membrane, because light can only travel along the membrane, not through the space between the two membranes. However, we can feel the gravitational pull of objects on the shadow membrane. There could be shadow galaxies, shadow stars and even shadow people who might be surprised to feel the gravitational pull of material from our membranes. For us, this kind of shadow object appears as dark matter, which is invisible matter. But its gravity can be felt.
In fact, we have evidence of dark matter in our own galaxy. The amount of material we can see is not enough for gravity to hold rotating galaxies together. Unless there is some dark matter, the galaxy will fly apart. Similarly, the amount of matter we observe in galaxy clusters isn't enough to keep them from spreading out, so there must be dark matter. Of course, shadow membranes are not necessary for dark matter. Dark matter may simply be some form of matter that is hard to observe, such as wimps, or brown dwarfs and low-mass stars that are never hot enough to burn hydrogen.
Because gravity diverges into the region between our membrane and the shadow membrane, the gravitational attraction between two neighboring objects on our membrane falls more sharply with distance than with electricity, because the latter is confined to the membrane. We may be able to measure the short-distance behaviour of gravity in the laboratory using instruments developed by Sir Cavendish of Cambridge. So far we haven't seen any differences with electricity, which means the membranes can't be more than a centimeter apart. This is small by astronomical standards, but huge compared with the upper bound of other extra dimensions. New measurements of gravity at short distances are being made to test the concept of a "membrane world". 
Gravity can bend space, so it can travel to extra dimensions (such as a linear function described by two unknowns) by moving through virtual time in parallel universes, so it can travel through time by gravity.
Zone time: a system of time measured in a uniform global time zone. When the sun is shining, it is twelve o 'clock at noon. But the time when the sun shines is different in different places. For example, it is 12 noon in Shanghai, and it takes five hours for residents of Moscow to see the sun. It's already 2pm in Sydney, Australia. So if all places use the local time standard, it will bring a lot of inconvenience to the administration, transportation, and daily life. To overcome this difficulty, astronomers came up with a solution: divide the world's longitude by 15 degrees, so that there are 24 zones. The uniform time standard is adopted in each area, which is called "zone time". The difference between adjacent regions is one hour. When people go east from one area to an adjacent area, they set their clocks one hour ahead. Go a few hours faster if you walk through a few areas. In contrast, when people moved westward from one area to an adjacent area, they set their clocks back one hour. Set back a few hours if you walk through a few areas. At airports and other transportation centers. The corresponding districts of the world's major cities are often illustrated to facilitate travelers.
