J updated NET-591:
------------------
Description:
In the class FTPTimeStampParserImpl,
the SimpleDateFormat hackFormatter
will throw an exception for certain datestrings, even though their
SimpleDateFormat pattern for the hackFormatter instance is correct ("MMM d
HH:mm yyyy")
when in an environment that has daylight savings, like the environment reported
in this bug report.
For example:
Line 123:
parsed = hackFormatter.parse(timeStampStrPlusYear, pp);
where timeStampStrPlusyear = "Mar 27 02:02 2016"
will fail but
timeStampStrPlusyear = "Mar 27 03:02 2016"
would work.
The problem is according to
http://blog.tier1app.com/2013/05/29/daylight-savings-time-problem-java/ that
because of the daylight saving, the time
02:02 doesn't exist in my timezone (thats true - timezone leap was 02:00 the
27th).
Setting the hackformatters lenient to true would make it work.
However I don't know if that's the right way for this project.

Looking around I found two suggestions that might fix these kind of problems in
the code.
