Abstract

A method for determining time spent on system shutdown is provided. The method may involve identifying a time at which a shutdown instruction is initiated during the system shutdown. Further, an exit time of an object that is the last to exit during the system shutdown may be identified. The time spent on the system shutdown may be determined based on the time at which the shutdown instruction is initiated and the exit time of the object that is the last to exit. The method for determining time spent on system shutdown may obtain the system time spent on the previous system shutdown regardless of the reason that the system was shut down. Further, the user may be instructed to optimize the system according to the time spent on system shutdown.

First claim

The invention claimed is:

1. A computer implemented method for determining time spent on system shutdown, comprising:
presetting a first program to receive a shutdown instruction the earliest during the system shutdown, a second program to receive the shutdown instruction the last during the system shutdown;
determining a time at which the first program receives the shutdown instruction;
determining an exit time of the second program; and
determining the time spent on the system shutdown based on the time at which the first program receives the shutdown instruction and the exit time of the second program.

2. The method according to claim 1 , further comprising:
searching, for each object in the system, for a time at which the object receives the shutdown instruction and an exit time of the object, wherein the search is conducted in a system log recorded during the system shutdown.

3. A terminal, comprising: a processor and a memory having processor-executable instructions stored therein, and the instructions when executed by the processor, configure the processor to:
preset a first program to receive a shutdown instruction the earliest during a system shutdown, a second program to receive the shutdown instruction the last during the system shutdown;
determine a time at which the first program receives the shutdown instruction;
determine an exit time of the second program; and
determine the time spent on the system shutdown based on the time at which the first program receives the shutdown instruction and the exit time of the second program.

4. The terminal according to claim 3 , wherein the processor is configured to:
a searching unit, configured to identify, for an object in the terminal, a time at which the object receives the shutdown instruction and an exit time of the object during the system shutdown.

5. A non-transitory storage medium comprising computer executable instructions, wherein the executable instructions are configured to implement a method for determining time spent on system shutdown, and the method comprises:
presetting a first program to receive a shutdown instruction the earliest during a system shutdown, a second program to receive the shutdown instruction the last during the system shutdown;
determining a time at which the first program receives the shutdown instruction;
determining an exit time of the second program; and
determining the time spent on the system shutdown based on the time at which the first program receives the shutdown instruction and the exit time of the second program.
