Before you start, know this important thing about the dates: Throughout the system a wide variety of dates is used. Helper function get_date_from_steve() in matrr.utils.databases.dingus.py is generally capable of parsing any format; however, I had to add couple of methods myself and update existing one to the new API - so be prepared.
Parsing date from the integer may be very tricky. If you have a number, say 40555, it could be a 2015 or 2011 year depending on what you choose as a base year 1900 or 1904. Steve so far always used 1904 base. Libre Calc (excel) uses 1900 base which leads to **WRONG** date when you look at the spreadsheet. So be cautions. If you are not sure - check the file names - often they contain some clues.
