            Console.WriteLine("Last Write Time of file(sample.txt) : " & dt1)

        Catch ex As FileNotFoundException
            Console.WriteLine("File does not exist")
        End Try
    End Sub
End Module

Time before set last write time in UTC format:
Last Write Time of file(sample.txt) : 09-01-2021 16:20:47
Time After set last write time in UTC format:
Last Write Time of file(sample.txt) : 09-01-2021 16:23:39
Press any key to continue . . .

In the above program, we created the module Module1 that contains the Main() function. The Main() function is the entry point for the program.

Here, we set the last write time of "sample.txt" file in UTC format using SetLastWriteTimeUtc() method of File class. Then we printed the updated last write time in UTC format on the console screen.
