Question

Consider the behavior of two machines in a distributed system. Both have clocks that are supposed to tick 1000 times per milliseconds. One of them actually does , but the other ticks only 990 times per milliseconds. If utc updates come in once a minute, what is the maximum clock skew that will occur?

Answer 1

The whole mechanism of computer system, works on the basis of clock ticks, which is very essential for calculations of the next jobs timing of work, and time needed to complete the existing process. While one clock ticks 1000 times per millisecond, and the other ticks 990 milliseconds, then there will be a synchronization trouble.

As the difference between both clock's tick is very small, it shall not be noticeable, but after some process have been completed, it will become clearly noticeable.
