A network analyst is tasked with configuring the date and time on a router using EXEC mode. The date must be set to January 1, 2020 and the time must be set to 12:00 am. Which command should be used?

The `clock timezone` command configures the router's local time zone and its offset from UTC, not the actual current date and time.

The `clock summer-time date` command is used to define specific dates for the beginning and end of daylight saving time, not to set the current time.

The `clock summer-time recurring` command configures a recurring rule for daylight saving time based on month, day, and week, not to set the current date and time.

The `clock set` command is utilized in privileged EXEC mode to manually configure the current time and date on a Cisco router. The command requires the time in HH:MM:SS format and the date in DAY MONTH YEAR format, such as `clock set 00:00:00 Jan 1 2020` for the specified requirements.
