Abstract
This document describes a general and flexible TLV (type-length-value
structure) for representing time-values, such as an interval or a
duration, using the generalized Mobile Ad hoc NETwork (MANET) packet/
message format. It defines two Message TLVs and two Address Block
TLVs for representing validity and interval times for MANET routing
protocols.

RFC 5497 Time TLV March 2009
1. Introduction
The generalized packet/message format [RFC5444] specifies a signaling
format that MANET routing protocols can employ for exchanging
protocol information. This format presents the ability to express
and associate attributes to packets, messages, or addresses, by way
of a general TLV (type-length-value) mechanism.
