CompTIA Linux+ Powered by LPI (LX0-104) — Question 31

What is true regarding the time in a Linux system?

Answer options

• A. The BIOS clock of a computer always indicates the current local time and time zone.
• B. Each application must convert the Unix time to the current time zone which is usually done by using standard libraries.
• C. When the system is on the network, each query for the current time leads to a new network connection to a time server.
• D. When the system time changes, running processes must be restarted in order to get the correct time.

Correct answer: B

Explanation

Option B is correct because applications in Linux typically rely on standard libraries to convert Unix time to the local time zone. Option A is incorrect since the BIOS clock does not always reflect the current local time and time zone accurately. Option C is wrong because most systems use time synchronization protocols that do not require a new connection for each time query. Option D is also incorrect; processes can usually read the updated system time without needing to restart.
