//here adding 24 hours to current date time
today.setHours( today.getHours() + 24 );  

// Setting Up Date Format after adding 24 hours to today's date
yyyy = today.getFullYear();
mm = today.getMonth()+1 ;
mm = (mm<10?'0':'')+mm;
dd = today.getDate();
dd = (dd<10?'0':'') + dd;

//Setting Up Date Format after adding 24 hours to today's date
var hr  =  today.getHours();//getting hour part from today's date.
var min =  today.getMinutes();//getting minutes part from today's date.
var sec =  today.getSeconds();//getting seconds part from today's date.

hr = (hr<10?'0':'') + hr;// if hr is less than 10 then append '0' before it to make 'hh' format
min = (min<10?'0':'') + min;// if min is less than 10 then append '0' before it to make 'mm' format
sec=(sec<10?'0':'') + sec;// if sec is less than 10 then append '0' before it to make 'ss' format

//Printing Desired Date and Time Format
document.write(yyyy+"-"+mm+"-"+dd+" "+hr+":"+min+":"+sec+"\n");
</script>

var today = new Date();

//here adding 24 hours to current date time

today.setHours( today.getHours() + 24 );

// Setting Up Date Format after adding 24 hours to today's date

yyyy = today.getFullYear();

mm = today.getMonth()+1 ;

mm = (mm<10?'0':'')+mm;

dd = today.getDate();

dd = (dd<10?'0':'') + dd;

//Setting Up Date Format after adding 24 hours to today's date

var hr = today.getHours();//getting hour part from today's date.

min = (min<10?'0':'') + min;// if min is less than 10 then append '0' before it to make 'mm' format

sec=(sec<10?'0':'') + sec;// if sec is less than 10 then append '0' before it to make 'ss' format

//Printing Desired Date and Time Format

document.write(yyyy+"-"+mm+"-"+dd+" "+hr+":"+min+":"+sec+"\n");

</script>

 dd = (today.getDate()<10?'0':'') + today.getDate();
 
//Setting up Time Format After adding the desired time to current date.
 hr = (today.getHours()<10?'0':'') + today.getHours();

Lets take a random date as “2020-07-18 21:32:20”


<script>
var today = new Date("2020-07-18 21:32:20");

//  here subtracting 5hours to current date time
today.setHours( today.getHours() - 5 );  

//  here subtracting 30minutes to current date time
today.setMinutes(today.getMinutes() - 30); 

//Setting up Date Format After adding the desired time to current date.
yyyy = today.getFullYear();
 mm = today.getMonth()+1 ;
 mm = (mm<10?'0':'')+mm;
 dd = (today.getDate()<10?'0':'') + today.getDate();
 
//Setting up Time Format After adding the desired time to current date.
 hr = (today.getHours()<10?'0':'') + today.getHours();
 min = (today.getMinutes()<10?'0':'') + today.getMinutes();
 sec=(today.getSeconds()<10?'0':'') + today.getSeconds();
document.write(yyyy+"-"+mm+"-"+dd+" "+hr+":"+min+":"+sec+"\n");
</script>

var today = new Date("2020-07-18 21:32:20");

// here subtracting 5hours to current date time

today.setHours( today.getHours() - 5 );

// here subtracting 30minutes to current date time
