I plan to test the clock performance on as many as TEN 2010 Trophy Cams. My interest is in using these Cams as security devices whereby I might wish to leave them untouched for up to six months. If the clock is substantially off (say 2 minutes per day as 2robinhood posted), that would result in the date stamp being over 5 hours off by the sixth month. If you own current or previous year Trophy Cams models, please let me know if you have had any problems with the performance of their clocks. [email protected]
