  3.3.13.  Generalized Time
 
  A value of the Generalized Time syntax is a character string
  representing a date and time.  The LDAP-specific encoding of a value
  of this syntax is a restriction of the format defined in [ISO8601],
  and is described by the following ABNF:
 
  century = 2(%x30-39) ; "00" to "99"
  year    = 2(%x30-39) ; "00" to "99"
  month   =   ( %x30 %x31-39 ) ; "01" (January) to "09"
            / ( %x31 %x30-32 ) ; "10" to "12"
  day     =   ( %x30 %x31-39 )    ; "01" to "09"
            / ( %x31-32 %x30-39 ) ; "10" to "29"
            / ( %x33 %x30-31 )    ; "30" to "31"
  hour    = ( %x30-31 %x30-39 ) / ( %x32 %x30-33 ) ; "00" to "23"
  minute  = %x30-35 %x30-39                        ; "00" to "59"
  second  =   ( %x30-35 %x30-39 )  ; "00" to "59"
            / ( %x36 %x30 )        ; "60" (a leap second)
 
  GeneralizedTime = century year month day hour
                       [ minute [ second ] ] [ fraction ]
                       g-time-zone
  fraction        = ( DOT / COMMA ) 1*(%x30-39)
  g-time-zone     = %x5A  ; "Z"
                    / g-differential
  g-differential  = ( MINUS / PLUS ) hour [ minute ]
  MINUS           = %x2D  ; minus sign ("-")
 
  The <DOT>, <COMMA> and <PLUS> rules are defined in [MODELS].
 
  The time value represents coordinated universal time (equivalent to
  Greenwich Mean Time) if the "Z" form of <g-time-zone> is used,
 
  otherwise the value represents a local time in the time zone
  indicated by <g-differential>.  In the latter case, coordinated
  universal time can be calculated by subtracting the differential from
  the local time.  The "Z" form of <g-time-zone> SHOULD be used in
  preference to <g-differential>.
 
  Examples:
     199412161032Z
     199412160532-0500
 
  Both example values represent the same coordinated universal time:
  10:32 AM, December 16, 1994.
 
  The LDAP definition for the Generalized Time syntax is:
 
  ( 1.3.6.1.4.1.1466.115.121.1.24 DESC 'Generalized Time' )
 
  This syntax corresponds to the GeneralizedTime ASN.1 type from
  [ASN.1], with the constraint that local time without a differential
  SHALL NOT be used.
