No. "Voltage" is the difference of electric potential between two points ... the 'pressure' that electrons would feel to move from one point to another if there's a conducting path. The actual flow of electrons between two points is electric "current".
because it show the period of time of something
A line segment is between two end points
Because a place can rotate around those two points as long as the line in on the plane. Two points defines a line. A plane requires 3 points.
Current is the flow of electric charge, not the total charge itself. It is called a net charge because in a circuit the movement of charge is a result of the difference in charges between different points, creating a flow of net charge.
The potential difference between two points in a circuit is the energy required per unit charge to move a charge between those points. It represents the work done by an electric field on a charge as it moves through the circuit.
The relationship between energy and charge is potential difference or voltage. Where a volt is defined as existing between two points in an electric field when one joule of energy is required to move a charge of one coulomb between the two points.

No, electric current flows due to the movement of charged particles, usually electrons. Two objects with the same charge can still have current flow between them if there is a potential difference (voltage) present.
Potential difference is the difference in electric potential between two points in an electric field. It is measured in volts and represents the work done per unit charge in moving a test charge between the two points.
