Quick Answer
The answer is the `show system clock` command, because it is the dedicated Junos operational mode command that displays the current system time, the configured time zone, and the daylight saving time status. Unlike `show system uptime`, which shows how long the device has been running, or `show configuration system ntp`, which only shows NTP settings, `show system clock` directly outputs the local time and the time zone offset from UTC, making it the precise tool for verifying time and time zone configuration. On the JNCIA-Junos exam, this question tests your ability to distinguish between operational commands that retrieve live system status versus configuration commands; a common trap is confusing `show system clock` with `show system uptime` or `show configuration system time-zone`. To remember it, think of a wall clock: you look at a clock to see the current time, so `show system clock` is your go-to for verifying the device’s current time and zone.
This JNCIA-JUNOS practice question tests your understanding of operational monitoring and maintenance. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator needs to verify the current time and time zone configured on the Juniper device. Which command should they use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
show system uptime
Why wrong: Shows uptime, not current time.
show system clock
Displays current system date and time.
show system information
Why wrong: Shows general system info, not time.
show system date
Why wrong: Not a valid command.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
show system clock
The correct command is 'show system clock' because it displays the current system time and time zone configured on the Juniper device. This command is specifically designed to show the local time, time zone offset, and whether daylight saving time is active, making it the precise tool for verifying time and time zone settings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
show system uptime
Why it's wrong here
Shows uptime, not current time.
show system clock
Why this is correct
Displays current system date and time.
Clue confirmation
The clue word "which command" in the question point toward this answer.

show system information
Why it's wrong here
Shows general system info, not time.
show system date
Why it's wrong here
Not a valid command.
Common exam traps
The trap here is that candidates confuse 'show system uptime' with time display, but uptime only shows elapsed time since boot, not the current clock time or time zone.
Trap categories for this question
Command / output trap
Shows uptime, not current time.
Detailed technical explanation
The 'show system clock' command retrieves the time from the device's system clock, which is maintained by the Junos kernel and can be synchronized via NTP (Network Time Protocol) or manually set. The output includes the time zone abbreviation (e.g., UTC, EST) and the offset from UTC, which is critical for logging timestamps and troubleshooting time-sensitive protocols like BGP or OSPF. In real-world scenarios, misconfigured time zones can cause log correlation failures or certificate validation errors, making this command essential for verification.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the JNCIA-JUNOS exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
