The command "date -d @${1473305798}" is used to convert a Unix timestamp to a readable date and time format.

Here's a breakdown of the different elements:

• "date" is the command itself, used to display the current date and time.
• "-d" is an option followed by an argument that specifies the date or time string to be used.
• "@" is used to indicate that the given timestamp should be interpreted as a Unix timestamp.
• "${1473305798}" is the Unix timestamp value represented in this example. Unix timestamps are the number of seconds that have passed since January 1, 1970, 00:00:00 UTC.

So, when you run this command, it will take the Unix timestamp 1473305798 and convert it into a human-readable date and time format, which will be displayed as the output.
