Restart files with XIOS

Hi,

Is there a way to write restart files with XIOS2.5? The restart file needs the time_step variable but I can’t find a way of including this - I’m not sure CROCO sends this information to XIOS at the moment (or if it does, I haven’t found it). Is this possible in CROCO because writing the restart file without XIOS is forming a bit of a bottleneck for me at the moment?
