From what I can tell, the Linux system clock defaults back to zero (1/1/1970 @ 00:00:00) every time the TV is powered up. My guess is that they are handling the time without using Linux's time services, probably through a CMOS/NVRAM device on the logic board that only exeDSP knows how to access. If you can figure out how to access the hardware clock, perhaps a solution similar to Red Hat's "hwclock" command that sets/retrieves a PC's CMOS time to match the Linux system clock could be developed?

One of the biggest annoyances with my TV so far has been that the on-screen clock isn't set, because I don't have the TV hooked up to an OTA or cable signal for automatic time sync and it's pointless to set it manually if it doesn't sync to an accurate source. I did notice that the Samsung 4600 BlueRay player's online manual mentioned that they support NTP on those devices, so perhaps the code from those devices may be of help?????
for me it looks like the tv has a hw clock and works with some kind of offset.
my setup is all channels terrestrial + one crypted dvbc
if i set the clock to auto in menu and set the date via telnet to correct time the display clock jump to some strange date in 2040, after switch off and on the tv this date in 2040 correct continues but system time is at 1970 (notice: as you wrote).

if somebody can figure out how the stuff realy works let me now.

ps: made some experiments with rtc drivers but looks there is no support for this board

you need to set TZ value in your script for time zone. Now your time should be GMT.


BTW, ntp doesn't affect your exeDSP time. Just only system time...
