Dear Piotr,
Dear All,

I received notice regarding problems with dates after 2038,
NetWorker reporter aborting with :

root# ./NSR_REPORTER_4.0.4P1_SOLARIS -s server -D "MM/DD/YY"
(...)
Cannot handle date (0, 0, 0, 11, 10, 2038) at Time/Local.pm 
line 101
Broken Pipe

I gave my code a look and reproduced the problem within seconds.
The problem is not within my code but with Perl not handling
dates properly after Jan 19, 2038.

Up to now, NetWorker reporter uses a 32-bit signed integer holding 
dates converted to Epoch seconds. Using 32-bits signed integer,
you can only represent dates (in GMT) from 
Fri Dec 13 20:45:52 1901 to Tue Jan 19 03:14:07 2038 (inclusive). 

I also gave NetWorker 7.1.2 (on W2K prof sp4) a try, setting 
browse and expiration dates after 19-JAN-2038. In most of my 
trials resulted in nsrmm dumps. Trials using year 2039 or higher
resulted in nsrmm invalid argument error or dumps.

I am trying to find a workaround/fix to that problem,
allowing NetWorker Reporting Utility to handle dates
after Jan 19 2038 but up to now, NetWorker Reporter will
die handling dates after Jan 19, 2038.

Warm regards,

Thierry
