[RegCNET] Minor problem related to idate1 & idate2 in ICBC for Nesting

[jagadish karmacharya]

Hi,
  I have encountered following two minor problems while doing Nesting wth May 2005 version of RegCM.
  
  1 seting IDATE1 in icbc.param to 1st time step of any month (eg   IDATE=1996080100) generates following error:
  ........
  ........ 
  ifc -tpp7 -O3 -cm -w -w90 -w95  -o ICBC ICBC.o cdc6hour.o  era6hour.o -L../../Commons/env/liblinuxold -lnetcdf -ludunits -Vaxlib
   NREC =       289280
   NSTART,NNNEND:        70981       70989
   IDATE1,IDATE2:   1996080100  1996080300
   Note that rotated Mercartor (ROTMER) projections are not supported by GrADS.
     Although not exact, the eta.u projection in GrADS is somewhat similar.
    FERRET, however, does support this projection.

  ========================
  
  2 Supposed for Nested run DATA/RegCM is linked with ATM.1996090100  (which contains data for whole month i.e. 120 time steps or upto  1996:10:1:0) and if I set IDATE2 =1996100100 in icbc.param following  error arise. ICBC file is generated but data is missing for 1996:10:1:0  in the resulting ICBC file. However if there is link to ATM.1996100100  as well then this is problem doesn't arise.
  Now, why it is not enough to link/run simaulation just upto 1996100100  ( which is contained in ATM.1996090100 file itself) in the  source/driving RegCM?
