tds_get_size_by_type for SYBMSDATE

Hi,
when I look into tds_types.h (which is build on misc/types.csv) there is 
function tds_get_size_by_type() used f.e. by dbconvert()
And for SYBMSDATE it returns 4 (IMO it is wrong set size=4 in types.csv)
Is it correct ?
(as far as I understand it should be size if struct which holds this 
data type i.e.:
there should be:
  case SYMBSDATE:
  case SYMBSTIME:
  case SYMBSDATETIME2:
  case SYMBSDATETIMEOFFSET:
     return sizeof(TDS_DATETIMEALL);

?
When I change it this way, it works as expected for me.
Thanks
