I'm not sure if this ticket is in the scope of NEMO ST.

Need a clear statement on this work, is it still relevant now and if so who is the new PI.

When NEMO CO6 is run with a 360_day calender, the time_counter of the output netcfd is liable to wrapping around. Although defined as a double precision varable in the netcdf it's values appear to be limited to be within ±2,147,483,648 - ±232

Therefore when running with seconds since 360_day and 1950-01-01 00:00:00, the values wrap 69 years after the origin, and then every 2*69 years.

This does not happen when the calendar is set to "gregorian", so it must be a bug.

I guess somewhere within nemo or xios, time counter must be defined as a short interger rather han a long integer.
