The problem that the system time is not right, the master is coming, and he is in a hurry

Change the BIOS battery and see if it's dead.

Hello friends, judging from your story, there are two reasons for this:

The first is: your motherboard (twist buckle) battery is out of power, coms, can't be saved, what time will not be saved, so every time after changing, shut down and turn on, back to the old way, the way to deal with it is to buy a new battery (the general battery is 5---8 yuan, the model is mainly CR-2032) to replace it, and re-set the disc or hard disk in the BIOS as the first boot item, and turn off the floppy drive, it's OK.

The second is: there is a problem with your COMS circuit, in this circuit there is a management time called the real crystal oscillator, this crystal oscillator has a problem, which time will naturally be wrong, when the two resonant capacitors in the COMS circuit, and which resistor has a problem, it will cause the COMS random memory to be unable to save the COMS, and the natural time can not be saved, where there will also be a mistake in the time and date you said, and it is changed in vain, in this case, it is necessary to repair the COMS circuit of the motherboardOnly when the crystal oscillator is repaired and the COMS circuit is repaired, the time will be saved and the BIOS will be saved

The motherboard battery is dead, and changing the battery is cheap.

There is a problem with the clock counter, and it is possible that the motherboard battery is dead.

There are 2 reasons for this.

1.The motherboard battery is dead, and when you turn on the computer after the power is completely turned off, the system time will become the original time of the motherboard.

2.Computer poisoning forces many operations to be performed after the system time is modified, and the modification of the system time will affect log file records, antivirus software updates, normal operation of software, etc. Of course, there are very few software conflicts that affect system time, but not every time.

Try to confirm the problem, buy a motherboard battery, kill and disinfect, sweep the Trojan, confirm that there is a problem with the system, and reinstall the system if you have time.

There are 4 reasons why I know this:

1.The motherboard battery is out of power (generally the motherboard battery can be used until the computer is scrapped, the motherboard battery is completely dead, and the motherboard battery returns to the initial time every time it is turned on).

2.The crystal that controls the time on the motherboard is broken.

3.If you use software that requires time authentication, the time of the machine will be automatically changed after use, and the time is the same as the server, but the time of that server is wrong. (See Digital Timestamps.)

4.The virus modification time makes the antivirus software invalid (generally the year is changed, which is different from your situation) does not change the battery, but the time in the properties of some files is not accurate, and there is no requirement for this can be ignored.
