The correct time is the one that is shown in the displayed image.

This is the time as set in the InfraCAM/BCAM camera menu, whereas the time reported in a report uses one of the standard fields of the JPEG file that is saved by the camera.
The April 2006 InfraCAM camera application software translates time incorrectly to give this effect. The same (erroneous) time is presented if you right click on an InfraCAM image and
select "Properties" - "Summary", field named "Date picture taken".

If you encounter this problem, please contact your nearest FLIR service point to update your camera.
Camera firmware later than April 2006 perfoms correctly in this respect.
