Answer:
(a)Applications Time Stamp Events
(b)S=0.5(W-)+
, where
≤W≤
+8.
Explanation:
Some applications assume that clocks always advance, so they could timestamp events under this assumption.
In our case we have the wrong timed clock, say W and the hardware clock H which is supposed to advance at a perfect rate.
We proceed to construct a software clock such that after 8 seconds we can replace the wrong timed clock with the software clock in good conditions.
Let us denote the software clock with S.
Then, S=c(W-)+
where:
=The current Time(10:27:54) and;
c is to be found.
We already know that S=+4 when W=
+8,
So:
S=c(W-)+
+4=c(
+8-
)+
4=8c
c=0.5
We obtain the formula
S=0.5(W-)+
, where
≤W≤
+8.
