Consider how two machines in a distributed system behave. Both have clocks that should be ticking at 950 times per millisecond. One of them does, but the other just ticks once every 900 milliseconds. What is the maximum clock skew that can occur if UTC updates are received once per minute?
Question 2Answer
a.
The maximum clock skew that can occur if UTC updates are received once per minute = 0.02 x 60 sec, or 1200 msec.
b.
The maximum clock skew that can occur if UTC updates are received once per minute = 0.04 x 60 sec, or 2400 msec.
c.
The maximum clock skew that can occur if UTC updates are received once per minute = 0.03 x 60 sec, or 1800 msec.
d.
The maximum clock skew that can occur if UTC updates are received once per minute = 0.05 x 60 sec, or 3000 msec.
