Symptom:

• The following message appears at the top of your Webstats page:
• WARNING: LastLine parameter in history file is 'YYYYMMDDHHMMSS' in the future.

Answer:

• It's just a warning from the last day's processing of statistics that results from the http logs being in UTC time and the server time being in EDT.  It does not cause an error in the statistical data, and can be disregarded.
