When I show stats, I try to change the date using the Set date… button, press now button and the entry field now has the correct date, time. Press OK but the date shown in stats panel is still the old one. In other words the new date does not seem to be being applied.
Michael I have determined it is a problem caused by regional date/time settings. I am using OS X 10.8.2 AND SV 2.9.5
Please try UK date/time settings and you will see that Now puts in UK date format DD/MM/YYYY, but the entry field appears still to expect YYYY/MM/DD format.
Hopefully something that can be fixed fairly easily.
