MATLAB: How do you write a program that gives the current time and day

currentdatetime

I am very new to programming, and cannot figure out how to run this program correctly. My work is shown below. Please Help!

time = clock ();

day = date ();

fprintf('The current date is %f\n', day);

fprintf('The current time is %0f\n', time);

d = datetime('now') ;
fprintf('The current date is %s\n', d);
The current date is 08-Feb-2021 05:19:58

>> help now
now    Current date and time as date number.
  ...
  FLOOR(now) is the current date and REM(now,1) is the current time.

t = datenum('18:06:00') - datenum('00:00:01');
seconds = t * 24 * 60 * 60;
