In relativity, proper time along a timelike world line is defined as the time as measured by a clock following that line. It is thus independent of coordinates, and is a Lorentz scalar. The proper time interval between two events on a world line is the change in proper time. This interval is the quantity of interest, since proper time itself is fixed only up to an arbitrary additive constant, namely the setting of the clock at some event along the world line. The proper time interval between two events depends not only on the events but also the world line connecting them, and hence on the motion of the clock between the events. It is expressed as an integral over the world line. An accelerated clock will measure a smaller elapsed time between two events than that measured by a non-accelerated (inertial) clock between the same two events. The twin paradox is an example of this effect.

The invention discloses an automatic expenditure management method and system. The management method comprises that each step in the whole expenditure flow is extracted into an event, and execution of each event needs N conditions; whether the N conditions of the event are met is determined according to a first predetermined time interval, if all of the N conditions are met, the event is executed, and otherwise, the event is not executed till all of the N conditions are determined to be met; when execution of the event is completed, a corresponding execution result is obtained, and the event is updated to an executed state; whether the execution result of each executed event is normal is determined according to a second predetermined time interval; and when it is detected that the execution result of certain event is abnormal, abnormity alarm is provided. According to the system and method, the expenditure flow can be managed automatically, each event in the expenditure flow can be operated at proper time, present manual execution is replaced, and the load of maintenance staff is alleviated.
