Exam LX0-104 topic 4 question 12 discussion

B. The skew in time between the system clock and the reference clock is observed and corrected by a NTP client. The main purpose of an NTP client is to synchronize the system clock of a computer with a reference clock, such as a trusted NTP server, to ensure that the computer's clock is accurate. The NTP client continuously measures the difference, or skew, between the system clock and the reference clock, and it makes small adjustments to the system clock to keep it synchronized with the reference clock. In contrast, options A and C relate to the relationship between the system clock and the hardware clock or the time zone setting, which are not directly related to the purpose of NTP. Option D relates to adjusting for Daylight Saving Time, which some NTP servers can provide information about, but this is typically handled by the operating system, not by the NTP client.
