Plug-in code

 * When dealing with time elapsed, it is common to append a post fix
 * such as d(day), h(hour), m(minute) or s(second) to a string in order to easily denote the brief duration
 * of the time span from now. This plug-in allows sorting to take these
 * indicates of size into account.
 * A counterpart type detection plug-in is also available.
 *  @name Time span
 *  @summary Sort abbreviated time span correctly (2d 3h, 2h 8m, 3m 8s, 30s, etc)
 *  @author Allan Jardine - datatables.net
 *  @example
 *    $('#example').DataTable( {
 *       columnDefs: [
 *         { type: 'time-elapsed-dhms', targets: 0 }
 *       ]
 *    } );

jQuery.fn.dataTable.ext.type.order['time-elapsed-dhms-pre'] = function(data) {

    var matches = data.match(/^(\d+(?:\.\d+)?)\s*([a-z]+)/i);
    var multipliers = {
        s: 1,
        m: 60,
        h: 3600,
        d: 86400

    if (matches) {
        var multiplier = multipliers[matches[2].toLowerCase()];
        return parseFloat(matches[1]) * multiplier;
    } else {
        return -1;


This plug-in is available on the DataTables CDN:


Note that if you are using multiple plug-ins, it is beneficial in terms of performance to combine the plug-ins into a single file and host it on your own server, rather than making multiple requests to the DataTables CDN.
