The Option Chains command will return only current options, not past ones. There is no API method that will return past option symbols, but we publish a text lists of past/expired option symbols in:

This list includes only past option symbols that traded at least once. Standard API commands will work on past option symbols. There is also a file which contains past equity symbols.

Also, the Level 1 Fundamental Message contains a field called Contract Months, fifth from the end (in protocol 6.2):
