[ferret_users] MONTH_GREGORIAN climatological axis

[Brockmann Patrick <Patrick.Brockmann@xxxxxx>]

Hi all,

Looking carefully  to the climatological axis of a gregorian calendar,
I don't understand why there an offset of 05:49:12  hours in
information given by TBOXLO
Though, TBOX is ok.

yes? use climatological_axes
yes? show axis/t MONTH_GREGORIAN
name       axis              # pts   start                end
MONTH_GREGORIAN TIME          12mi   16-JAN 12:00         15-DEC 17:49
T0 = 01-JAN-0000 00:00:00
  Axis span (to cell edges) = 365.2425 (modulo length = axis span)
