Hi all....  
Here i am trying to update @timestamp field every time when i partially update the doc

```auto
POST /titanic_kfk/doc/22/_update?pretty
{
  "doc": { "@timestamp": 1508756153000 }
}

```

but in the above statement i have mentioned a static value for @timestamp field  
but i would like to know if there is any date function **like NOW() in MySql** so that i can use that function instead of static epoch values .

Please suggest me the possible ways to do that.

Thank You.
