TL-MR3020 timesave - doesn't work

Hi,

so I have trouble getting the timesave to work. I build my box on wednesday as explained in the guide.
Only problem I have is at point 3 under Post-Installation

Quote
3. Activate the “timesave functionality” once:
/etc/init.d/piratebox timesave

After that it says

Quote
Placing Timerecover on Startup
Activating cron-service...
done

But when I turn off my box and later turn it on again, the date is Thu Jan 1 00:00:00 UTC 1970 again and I have to set the correct date and time manually again.

I have a TP-Link TL-MR3020 and a SanDisk USB STICK CRUZER 32GB Extreme USB 3.0.

So, what did I do wrong? Please help :)

Also: I'm new to this kind of stuff and english isn't my first language.
