how do you add zeros to dates when reading in file? For example the file i am reading has dates as 201433 should be 20140303 or 2014133 should be 20141303 or 2013313 should be 20140313
If this is the case, you are having a dirty data problem beyond any programming can fix. First, make sure your data is YYYYMMDD or YYYYDDMM. Then Consider this: 2015111. Is it 20150111 or 20151101?
At this point the question is can you go to the data source and have them clean up the dates, either provide the leading 0 as needed or separate year, month and day columns.
