Reports have 1899 listed as Begin Time

I created a custom report with BEXEC 2012. I used advanced fields and select "Begin Time" and "End Time" and other settings. Ran the report and the Begin/End times were 12/29/1899. 1899?  Report date is accurate. Any ideas? I certainly cannot submit this report as proof. I did test other reports, not all of course, and those tested revealed the correct dates.
