At dm7080 (latest exp image) I have since a couple of days the wrong system time: it is 6 minutes ahead. I changed to diff. satellites to eliminate the possibility of a wrong tp time. I also stopped E2 and changed /etc/enigma2/settings to: "config.misc.useTransponderTime=false" but after restarting E2 and even after a complete reboot I get again the same wrong systemtime. Also in network settings (menu key) I set ntpautoupdate to manual (maybe the same effect as changing E2 manually) but again wrong system time.
I also tried to change the systemtime with the command date MMDDHHmm and for 1 second the systemtime is ok but than the systemtime at my dm7080 is again wrong.
I checked at my dm900 (with also latest exp image) and there everything is ok. Very weird, but what can I do....
[Later] I also tried the plugin dvbtime, but did not help either.
