/**
 * This plug-in provides the ability to sort columns that contains time
 * information in the most common formats used. It will automatically detect
 * those date types.
 *
 * Please note that this plug-in is **deprecated*. The
 * [datetime](//datatables.net/blog/2014-12-18) plug-in provides enhanced
 * functionality and flexibility.
 *
 *  @name Time (dd/mm/YY)
 *  @summary Sort Times in the formats: `hh:mm, hh:mm:ss, hh:mm tt, hh:mm:ss tt`
 *    e.g. '22:50, 22:50:40, 10:50 pm, 10:50:40 pm' 
 *    am and pm are not case sensitive. white space is not compulsory
