title: how to assign date time to highchart with intervals and date start
body: <p>HI In highchart is there any way to give time on x-axis as below</p>
  
  <p>1) pass start time<br>
  2) give an array of time points<br>
  3) give unit of time</p>
  
  <p>for example</p>
  
  <pre>
  start time will set as
  pointStart: Date.UTC(timeArr[3],timeArr[1],timeArr[2],timeArr[4],timeArr[5])
  where timeArr[3] -> year
  timeArr[3] -> year
  timeArr[1] -> month
  timeArr[2] -> day of month
  timeArr[4] -> hour
  timeArr[5] -> minute
  
  now set time intervals array as below
  [0,60,120,180,240]
  
  now give unit of time as 1000(which tells time in array is in seconds)
  </pre>
  
  <p>And then highchart plot the x-axis by starting from start date and then pick interval from time array and add to start time and create time for next datapoint</p>
  
  <p>I ask this question because our old application uses JClass chart and I am converting from that and that works on the logic I give</p>
