ExtUTCTime ::= OCTET STRING(SIZE(11 | 13))
    -- format is YYMMDDHHMMZ or YYYYMMDDHHMMZ
    --   where: YY   - last two digits of year (only years
    --                 between 1900-1999)
    --          YYYY - last four digits of the year (any year)

    -- For example, "9502192015Z" and "199502192015Z" represent
    -- 8:15pm GMT on 19 February 1995. Years after 1999 must use

Gauge32 ::=

-- an unsigned 32-bit quantity
-- indistinguishable from Gauge32
Unsigned32 ::=

-- hundredths of seconds since an epoch
TimeTicks ::=

-- for backward-compatibility only
Opaque ::=
    [APPLICATION 4]
