Wrong system date

Have a problem - current system date refers to 10.4.2015 this causes EPG malfunction etc.

I installed   enigma2-plugin-systemplugins-systemtime_1.0-rc3_mipsel.ipk  

And tried to set up proper time and date - it works via transponder and via internet either, but proper date was never saved, and Vu+ Ultimo is back in 2015

Any idea how to save a proper date to my enigma box ?

Thanks
