So you have opened the Net Barchart report in this case. And you are 
running on Windows.
Which verson of Windows ? And which version of GnuCash ?

The values in this function call are unusual in my opinion.

The unusual date value of 0 in the above call to gnc:timepair-start-day-
time is interpreted as Dec 31, 1969, which is an invalid date on Windows 
(it's a valid date on Linux and OS X though). Hence the error in your 
report.

The question now is where does this invalid selection come from. Which 
period (start date and end date) are set for this report ?

P.S. The warning about perl is harmless. It only means you didn't set up 
Finance::Quote (yet), so you won't be able to fetch online quotes. 
That's totally irrelevant to the report issue you are experiencing.
