There is no conversion API right now, but we could define xntbase_convert(inbase, rtdm_base), with inbase being extracted from xnthread_timebase(xnpod_current_thread()) for primary context services. The question remains open on how to get the inbase pointer for seconday mode callers though. -- Philippe.
