This object is another of this module's shared, reusable varbinds, defined to report a date-and-time value representing the current MIB release or version, for attachment to vendor-specific notifications that want to indicate which MIB revision is in use. An admin can use this value, if provided in a trap, to determine when the MIB module implemented by the sending device was last revised. For example, a trap carrying this common varbind might report mibRelease as a timestamp corresponding to the MIB's most recent published revision date.
