Dear all:
When I running RegCM from Dec23 2006 to Feb1 2007, I meet a problm:

I wonder what the problem is ? When I running from Jun25 2006 to Aug1 2006(in summer). No such problem.
in getdat.f
calday = dble(julday)+(NNNNNN-NSTRT0)/4.+(xtime/60.+gmt)/24.
in file regcm.in
$restartparam
ifrest = .false. ,
idate0 = 2006122300,
idate1 = 2006122300,
idate2 = 2007010100,
nslice = 120,
$
$timeparam
radfrq = 30.,
abemh = 18.,
abatm = 240.,
dt = 120.,
ibdyfrq = 6,
$
I have ever run by time step is 90s ,the NaN is remain.

Please help me!
