I am reviewing a contract that includes clauses (for example 1052.216-98 TASK ORDERS (DEC 2008) This appears to be a DTARS Clause when I looked it up on the FARSITE. I'm confused about the use of a 2008 clause in a new contract that I was not expected the inclusion of DTARS Clauses. In addition, I cannot locate the clause on the FARSITE. Advice? There are several 1052 Clauses in the contract. The language in some is very outdated. Suggestions on negotiating these clauses or researching them better?
