Hi Smiling Dragon, cfajohnson, Scrutinizer, & Aia,
If you look closely at the 1st post in this thread, you'll notice that the request is to find timestamps in unspecified fields in a CSV formatted file where the input timestamps are in the format MM/DD/YYYY HH:MM:SS and the output timestamps are supposed to be one month later in the format DD/Mon/YYYY HH:MM:SS.
So, there is no reason to believe that using / as a field separator on an input line will yield only three fields, that the first field will just contain a month number, nor that the third field will only contain a year and a timestamp. None of the code suggested so far makes any attempt to adjust the output month, to adjust the day field if the output month has fewer days than the input month, nor to adjust the year if the input month is 12.
Three days ago (less than an hour after the original post), I asked the submitter to provide us with more details and to show us what had been tried to solve this problem. I figured that the code that would be shown to us would clarify if the conversion from month number 06 to abbreviated month name Jul was intentional or a typo, would clarify if the field separator in the CSV file format was a comma or some other character, and would clarify whether every input field needed to be processed or if only certain fields need to be processed. Unfortunately, I am still waiting for a response.
