set time date in raspberry pi b+ without internet

[bmarkus]

dpkg-something, eh? Are we talking about piCore, the Raspberry Pi port of Tiny Core Linux? Dion't think so....

that worked.
does this try to get time from NTP ?
startup message shows 'skipping RTC' .

I dont think Raspberry Pi has a RTC so that's correct (I have seen several projects to add an RTC to Raspberry Pi too BTW).

If I let my RPi turned on, of course, the date will change but when I turn it off and restart it, the date is still Tue Sep   9 xx:xx:xx CEST 2014

I imagine without a real-time clock, the RPi probably forgets the time every time you start? Which means you must manually set the daye & time OR add a RTC circuit OR use NTP.
