/**
 * Retrieves the date parsed from the header of a log. Unless otherwise defined in the properties file,
 * we have to use some logic to figure out the year. After parsing the date, we need to correct the time-zone. 
 * Then we set the dateTime to the current year. Now we need to check the dateTime and see if it's after today.
 * The logic is as follows:
 *      - If Log time-stamp < End of day of today 
 *          (comparing Month, Day, Hour, Minutes, Seconds, with year missing), 
 *          assume it's this year.
 *      - If Log time-stamp > End of day of today 
 *          (comparing Month, Day, Hour, Minutes, Seconds, with year missing), 
 *          assume it's previous year.
 * 
 * The following restrictions will be made to customer for BulkLoad:
 *      - Cannot upload logs older than 11 months.
 *      - Cannot upload logs that are continuous for more than 11 months.
 * 
 * Note: END OF TODAY is purposely chosen instead of START OF TODAY in case a user bulk loads logs that 
 * belongs to today.  It's not possible/likely that a user would bulk load logs from last year of the 
 * same day with the restriction we specified above.
 * @param source the source name string value.
 * @param s the date and time string value.
 * @return Date object with date/time-stamp of the Linux log.
