Overview#
UTCTime (Deprecated) LDAPSyntaxes is a character string representing a DateTime to a precision of one minute or one second.UTCTime has an OID of:
The year is given as a two-digit number. The LDAP-specific encoding of a value of this syntax follows the format defined in ASN.1 for the UTCTime type and is described by the following ABNF:
UTCTime = year month day hour minute [ second ] [ u-time-zone ]
u-time-zone = %x5A ; "Z"
/ u-differential
u-differential = ( MINUS / PLUS ) hour minute
The above ABNF allows character strings that do not represent valid dates (in the Gregorian calendar) and/or valid times. Such character strings SHOULD be considered invalid for this syntax.
The time value represents coordinated universal time if the "Z" form of <u-time-zone> is used; otherwise, the value represents a local time. In the latter case, if <u-differential> is provided, then coordinated universal time can be calculated by subtracting the differential from the local time. The <u-time-zone> SHOULD be present in time values, and the "Z" form of <u-time-zone> SHOULD be used in preference to <u-differential>.
The LDAP definition for the UTC Time syntax is:
( 1.3.6.1.4.1.1466.115.121.1.53 DESC 'UTC Time' )
Microsoft Active Directory and UTCTime and GeneralizedTime#
Microsoft Active Directory uses OID to represent both UTCTime and GeneralizedTime.UTCTime is also a X.500 ASN.1 Data type
