Add Time

Sandeep Gangadharan Sep 21, 2005

Use this script to add time - in the form of seconds, minutes, or hours - to the current time.

Current Time:

Add Hours:	Add Minutes:	Add Seconds:

Scheduled Time:

The JavaScript Source: Time and Date: Add Time

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Command-s). The script is yours!!!

<!-- THREE STEPS TO INSTALL ADD TIME:

1.  Copy the coding into the HEAD of your HTML document
  2.  Add the onLoad event handler into the BODY tag
  3.  Put the last coding into the BODY of your HTML document  -->

<HEAD>

function sivamtime() {
  now=new Date();
  hour=now.getHours();
  min=now.getMinutes();
  sec=now.getSeconds();

if (min<=9) { min="0"+min; }
  if (sec<=9) { sec="0"+sec; }
  if (hour<10) { hour="0"+hour; }

document.hours.clock.value = hour;
  document.minutes.clock.value = min;
  document.seconds.clock.value = sec;
  setTimeout("sivamtime()", 1000);
}

function sivamtime3() {
  now5=new Date();

addH = document.addhours.addclock.value;
  addM = document.addminutes.addclock.value;
  addS = document.addseconds.addclock.value;

hour3 = parseInt(addH) + now5.getHours();
  min3 = parseInt(addM) + now5.getMinutes();
  sec3 = parseInt(addS) + now5.getSeconds();

if (sec3>=60) { sec3 = -(60 - sec3); min3 = parseInt(min3)+1; }
  if (min3>=60) { min3 = -(60 - min3); hour3 = parseInt(hour3)+1; }
  if (hour3>=24) { hour3 = -(24 - hour3); }
  if (sec3<=9) { sec3="0"+sec3; }
  if (min3<=9) { min3="0"+min3; }
  if (hour3<=9) { hour3="0"+hour3; }
  if ((addS>59) || (addM>59) || (addH>23)) { window.alert('Invalid Input!!'); return false; }
  if ((addS.length > 2) || (addM.length > 2) || (addH.length > 2)) { window.alert('Invalid Input!!'); return false; }
  if ((addS.indexOf('-') != -1) || (addM.indexOf('-') != -1) || (addH.indexOf('-') != -1)) { window.alert('Invalid Input!!'); return false; }

document.hours1.clock1.value = hour3;
  document.minutes1.clock1.value = min3;
  document.seconds1.clock1.value = sec3;
  setTimeout("sivamtime3()", 1000);
}
