The PocketBook runs fairly generic Linux system.
I think that it would be a major undertaking to hack the Linux kernel in such a way that it does not need the time information.
The kernel timestamps everything. From file access times to running processes, threads, ...
Even if you disconnect the main battery the hardware clock continues running. I have disconnected my battery once and I did not have to set the time again. So I think that it has a separate very small battery.
