Breeze dates are not materialized correctly for mapped entities

Question

I have a date property coming into Breeze from my server. It looks like this in the JSON

"CreateTime":"2014-05-22T00:00:00.000"

The property is mapped in the metadata like this:

{
    "name":"CreateTime",
    "type":"Edm.DateTime",
    "nullable":"false",
    "precision":"7"
}

In the query results, however, the date always ends up as the epoch (Jan 1, 1970). However, this only happens when the entity is mapped in Breeze. If I select against the entity so that I am returning an unmapped type the date is sent across the wire identically, but it works fine.

How can I get dates to materialize correctly for mapped entities?

Using Breeze v1.4.11

Update

Here is the result of calling getEntityType on my entity:

{
   "shortName":"VDisplayEvent",
   "namespace":"Model",
   "autoGeneratedKeyType":"None",
   "defaultResourceName":"VDisplayEvents1",
   "dataProperties":[
      // Other properties...
      {
         "name":"createTime",
         "dataType":"DateTime",
         "isNullable":false,
         "defaultValue":"1900-01-01T08:00:00.000Z",
         "validators":[
            {
               "name":"required"
            },
            {
               "name":"date"
            }
         ]
      },
      // Other properties...
   ]
}

Found the problem, and it's not an issue with Breeze. My application is using a theme, which had a dependency on date.js. Apparently, date.js overrides Javascript's Date.parse() function, which is used by Breeze's DataType.parseDateAsUTC().

Date.js's Date.parse() function just returns null when confronted with parsing a date string like the one above, which was causing the issue.
