Local fix

Problem summary

• When the customer sets historical sampling interval to 1 minute,
  the data is actually recorded every 62 seconds.  This is because
  the agent takes 2 seconds for each sample and the sample expiry
  timer does not take this time into account while setting the
  timer to expire the next time.
  

Problem conclusion

• The code has been modified to keep track of the time taken to
  get the sample from the agent, and then subtract it from the
  sampling interval while setting the next timer expiration.
  
  Note:
  If the sampling interval is less than 1 minute and activity is
  high, the data collection time might be longer.  This might have
  an effect on the expiration time and number of samples taken.
  This is beyond program control.
