The command "date --rfc-3339=s" is used to display the current date and time in a specific format defined by the RFC 3339 standard.
The "date" command is a program typically found in Unix-based operating systems that allows users to view or modify the system's date and time settings.
The option "--rfc-3339=s" is used to specify the format in which the date and time should be displayed. In this case, "s" stands for "seconds" precision, which means the command will display the date and time with precision up to the seconds level.
The RFC 3339 standard defines a date and time format that is widely accepted and used in the Internet community for representing dates and times in a human-readable and machine-readable format. The "--rfc-3339=s" option ensures that the date and time output adheres to this standard.
