RTC does not work on Iris with Colibri VF61 on WEC2013

Am using Iris Rev 1.1 board with Colibri VF61. I have inserted the battery on the board, but still the date and time are changing after restarting the board. Am using Win ce 2013. Any ideas why it is happening??

Not sure if this will help but i have just had a similar issue on the ixora board. I checked the registry settings stated on this page and they was correct. For some reason from that point it seems to work.

I found the solution. After setting the date and time, you just have to go to Start> Program Files> Colibri Tools and click on SaveReg.
