Which of the following tasks can be accomplished using the command date? (Choose TWO correct answers.)

The date command is used to display and set the system date and time. It can also be used to print

the time in different formats and calculate future and past dates. The date command has the

following syntax:

date [option]... [+format]

The format controls begin with the % symbol and are substituted by their current values. For

example, to display the current year, month, and day, we can use the following command:

date +"Year: %Y, Month: %m, Day: %d"

To set the system clock manually, we can use the --set or -s option followed by the date and time

string. For example, to set the date and time to 5:30 PM, May 13, 2010, we can use the following

command:

date --set="20100513 05:30"

The other tasks are not possible with the date command because:

Synchronize the hardware and system clocks: The date command cannot synchronize the hardware

and system clocks. To do this, we need to use the hwclock command, which can read or set the

hardware clock, and also synchronize it with the system clock.

Set the hardware clock: The date command cannot set the hardware clock. To do this, we need to use

the hwclock command with the --systohc or -w option, which will copy the system time to the

hardware clock.

Update the time via NTP: The date command cannot update the time via NTP (Network Time

Protocol). To do this, we need to use the ntpdate command, which will query an NTP server and set

the system clock accordingly.
