[Developers] determining when a property is updated

[Augusto Callejas]

hi-

i updated the "name" property for an object:

{
  "guid" : "#9202a8c04000641f80000000076302d2",
  "name" : {
    "connect" : "update",
    "lang" : "/lang/en",
    "value" : "zzz"
  }
}

and now i'd like to be able to detect in general when
a property is updated like this.  there is the 'timestamp'
property, but that only applies the the object and when
it was created, not when a property of that object was
created:

{
  "guid" : "#9202a8c04000641f80000000076302d2",
  "name" : null,
  "timestamp" : null
}

is there any way to determine this?

thanks,
augusto.
