RTC of AM335x is not Updated with QProcess Class

[praveen0991kr]

I have made one application in which i have to update my system date and time:
Qt 5.0.1
Linux Environment

when i am working with Ubuntu 12.04 and after running application as i press pushbutton date and time is updated on system and after restart of PC it shows updated date and time;

but the same application when i run on my AM335x device with linux environment:
After pressing pushbutton it shows updated date and time as required but when i restart my device it show previous data i.e : date time that might be store in SDK files or AM335x system files

My Question is how to update Date and Time Values in AM335x based device system files.

Is the AM335x part of a BeagleBone system? If so, I think you'll find that, as the BB doesn't have a hardware clock source, the system time is probably set via "NTP":http://en.wikipedia.org/wiki/Network_Time_Protocol on boot and is therefore probably overwriting/ignoring your changes.

As this is is more of a system/OS question you might get more luck on one of the BB/embedded linux forums.
