The correct answer is D
A. The possibility of omission or duplication of transactions will not happen due to lack of clock synchronization.
B. Data transfer has nothing to do with the time stamp.
C. While the time stamp on an email may not be accurate, this is not a significant issue.
D. During an investigation of incidents, audit logs are used as evidence, and the time stamp information in them is useful. If the clocks are not synchronized, investigations will be more difficult because a time line of events occurring on different systems might not be easily established.
