[Developers] invalid /type/datetime value?

[Augusto Callejas]

hi-

i posed a query:
====
[
  {
    "/common/topic/alias" : [
      {
        "lang" : "/lang/en",
        "link" : {
          "timestamp" : null,
          "timestamp>=" : "2008-06-23T16:12:55-07:00"
        },
        "optional" : true,
        "value" : null
      }
    ],
    "/type/object/guid" : null,
    "/type/object/name" : [
      {
        "lang" : "/lang/en",
        "link" : {
          "timestamp" : null,
          "timestamp>=" : "2008-06-23T16:12:55-07:00"
        },
        "optional" : true,
        "value" : null
      }
    ],
    "timestamp" : null,
    "type" : "/user/augusto/default_domain/type2"
  }
]
====
but i got back:
====
{
  "code" : "/api/status/ok",
  "q1" : {
    "code" : "/api/status/error",
    "messages" : [
      {
        "code" : "/api/status/error/mql/graph",
        "info" : {
          "detail" : "on line 1, column 289: \"2008-06-23T16:12:55-07:00\":
expected a timestamp value",
          "subclass" : "SEMANTICS"
        },
        "message" : "error SEMANTICS: on line 1, column 289:
\"2008-06-23T16:12:55-07:00\": expected a timestamp value"
      }
    ]
  },
  "status" : "200 OK"
}
====

the problem is with:

  "2008-06-23T16:12:55-07:00"

i thought this is a valid date?

thanks,
augusto.
