 1.  Introduction

   This document specifies a new ASN.1 [ASN1] type for representing    time: BinaryTime.  This ASN.1 type can be used to represent date and    time values.

   This document also specifies an alternative to the signing-time    attribute used with the Cryptographic Message Syntax [CMS] SignedData    and AuthenticatedData content types, allowing the BinaryTime type to    be used instead of the traditional UTCTime and GeneralizedTime types.
