Javascript Time Functions

by Alexis Hope, 26 Nov 2010

A quick note on converting javascript time stamps to human-readable format. I had been working on a travel calculator with new Google Maps v3 which required this for UI.

The following function takes a javascript Date object as a parameter and converts it to a human-readable string.

The functions themselves are simplistic. But can be tedious to work out in a pinch. Also, the pluralise function is a good starting point for converting other values to human-friendly names. While it won’t cover all edge cases it services the majority.

/*
 * format time from Date to string
 * @param time:Date
 * return string
 **/
function timeNice(time) {
    var hours = time.getHours();
    var minutes = time.getMinutes();
    var nicetime = hours + ' ' + pluralize(hours, 'hour', 's') + ' ' 
          + minutes + ' ' + pluralize(minutes, 'minute', 's');
    return nicetime;
}

function pluralize (count, word, suffix) {
  return count === 1 ? word : word + suffix;
}
