Please note that RegCM has internal date functions supporting different calendar 
types only from version 4.2. In previous versions, only gregorian calendar was 
supported (i.e. with leap year). If you must stick to 4.1.1, when using 
noleap/360dys calendar input GCMs, your only option is to fake the RegCM.
Just look at the code, and force the jump from 28 of February to March, 1st in 
mod_tendency at line 2209 where the addhours subroutine is called. Something like:

if (lmonth == 2 .and. lday == 28 .and. lhours > 18) then
   call addhours(ldatez, ibdyfrq+24)
else
   call addhours(ldatez, ibdyfrq)
end if

To use instead a 360 days calendar, a more in deep modification to the addhour 
function itself would be required.

Another option would be to upgrade to the model latest version.

Ciao!
