How to get value of column ValidToTZId, ValidFromTZId in LogisticsPostalAddress table use X++ ?

Can everyone help me, how to get value of colunm ValidToTZId, ValidFromTZId in LogisticsPostalAddress use X++

Normally, I create an object of LogisticsPostalAddress , an I can get value of columns in table that use property of table, but with two column ValidToTZId, ValidFromTZId, I can't apply that way

My code like this:

LogisticsPostalAddress logisticsPostalAddress;
LogisticsPostalAddressContract logisticsPostalAddressObj;

// code successfully run
logisticsPostalAddressObj.paramADDRESS(logisticsPostalAddress.Address);
logisticsPostalAddressObj.paramSTATE(logisticsPostalAddress.State);
...

// not find property VALIDTOTZID
logisticsPostalAddressObj.paramVALIDTOTZID();
// not find property VALIDFROMTZID
logisticsPostalAddressObj.paramVALIDFROMTZID();

Moreover, I found that the structure of table LogisticsPostalAddress has column  ValidToTZId and ValidFromTZId

Thank you,
