title: Parsing HH:MM in bash shell?
body: <p>I am writing a bash script:
  I have a parameter set to 02:00 eg. PARAM=02:00.</p>
  
  <p>I have a date in the format YYYYYMMDDHHMMSS, eg SAMPLE_DATE=20160101000000.</p>
  
  <p>How can I add this PARAM to this SAMPLE_DATE? </p>
  
  <p>eg: SAMPLE_DATE+PARAM = (20160101000000+02:00) = 20160101020000.</p>
  
  <p>I have split PARAM got the minutes and then using date api I added these minutes to the date, but Could there be any other better option for this one?</p>
