Is it possible to change the uptime value?

Question

linux

Actually the question is in the title.

Answer 1

Change yourself or wonder if someone could change?
There is such a bug - if the time is lost on the PC, and after that the ntp server pulls up the correct time, then the value can be very large (for example, the PC knocks down the time because the BIOS battery is dead, and the initial time is January 1, 1999. In this case, the system when turned on, it will remember such a turn-on date, but when the ntp server sets the correct time, then in uptime it will show that the system has been turned on for 20 years and a tail).
