How to set a DateTime property to an artifact

If our use case is to search for items which promoted after a specific date there is a way to set a DateTime property to an artifact, we made an example for that:

In case a user would like to search for an item based on an artifact's promotion date, the user can set a DateTime artifact property which later he can use to search.
For example:

1. Add DateTime property to an artifact by Set Item Properties rest API command:

curl -uadmin:password -X PUT "http://localhost:8081/artifactory/api/storage/npm-local/.npm/npmtest/npmtest-1.0.2.json?properties=PromotedOnProdDate=$(date +%Y-%m-%dT%H:%M:%OS%z)"

2. Verify that the Item Properties has been modified:

curl -uadmin:password -X GET "http://localhost:8081/artifactory/api/storage/npm-local/.npm/npmtest/npmtest-1.0.2.json?properties"

{
  "properties" : {
    "PromotedOnProdDate" : [ "2019-04-17T13:54:28 0300" ]
  },
  "uri" : "http://localhost:8081/artifactory/api/storage/npm-local/.npm/npmtest/npmtest-1.0.2.json"
}

3. Search with aql for items that match the criteria:

curl -uadmin:password -XPOST "http://localhost:8081/artifactory/api/search/aql" -H "Content-Type: text/plain" -d 'items.find({"@PromotedOnProdDate" : {"$gt" : "2019-07-16T19:20:30.45+01:00"}})
'

{
"results" : [ {
  "repo" : "npm-local",
  "path" : ".npm/npmtest",
  "name" : "npmtest-1.0.2.json",
  "type" : "file",
  "size" : 631,
  "created" : "2019-02-06T09:53:59.152Z",
  "created_by" : "_system_",
  "modified" : "2019-02-06T09:53:59.124Z",
  "modified_by" : "_system_",
  "updated" : "2019-02-06T09:53:59.153Z"
} ],
"range" : {
  "start_pos" : 0,
  "end_pos" : 1,
  "total" : 1
}
}
