javascript - Convert time interval given in seconds into more human readable form

Question

I need a code snippet for converting amount of time given by number of seconds into some human readable form. The function should receive a number and output a string like this:

34 seconds 
12 minutes 
4 hours 
5 days 
4 months
1 year

No formatting required, hard-coded format will go.

Answer 1

 function secondsToString(seconds)
{
var numyears = Math.floor(seconds / 31536000);
var numdays = Math.floor((seconds % 31536000) / 86400); 
var numhours = Math.floor(((seconds % 31536000) % 86400) / 3600);
var numminutes = Math.floor((((seconds % 31536000) % 86400) % 3600) / 60);
var numseconds = (((seconds % 31536000) % 86400) % 3600) % 60;
return numyears + " years " +  numdays + " days " + numhours + " hours " + numminutes + " minutes " + numseconds + " seconds";

}
