I am querying a Sybase DB via PHP ODBC driver. All of my date columns are returning just blank strings.
Does anyone know if there are any settings on the ODBC driver or connection string options I can pass to prevent this issue?

$conn  =  odbc_connect("server","name","pass");
$getsql  = "SELECT " . implode(', ', $colnames) . " FROM {$tblname} ". 

$getqry = odbc_exec( $conn, $getsql);
while($getrow = odbc_fetch_array($getqry)) {
  // In above all date columns have an empty string
  // If I query isql dates are OK, other columns are all OK
