+* The class offers methods to create, access, and clone expiration headers, with a core focus on representing the integer-based expires time for SIP communication protocols. 
+* It supports basic header manipulation by storing an expires value and allowing retrieval and duplication of that value, 
+* facilitating session timeout and lifecycle management in SIP-based network interactions."
