Where to look up current POS difficulty in ppcoin-qt ?

How often does POS difficulty (not POW difficulty) retargets ? The white paper only says it is adjusted continuously.

Via the RPC command “getdifficulty”.

But the difficulty is not exactly what is used internally. The calculation of difficulty from the internal “nBits” is here: https://github.com/ppcoin/ppcoin/blob/master/src/bitcoinrpc.cpp#L73-L89

After each block. The difficulty is calculated from the previous difficulty, the time between the last two blocks, and some constants.

It’s here: https://github.com/ppcoin/ppcoin/blob/master/src/main.cpp#L916-L923
This code handles both POS and POW.

Oops that is right. Why do I have the memory that the command only returns the POW difficulty… :-[

It is also explained here About the block.nBits
