title: how to get current time using cypher
body: <p>lets say for example, I have ten nodes with a name and time property. i have used the timestamp() function but it returns a value, that is the difference between the current time and the 1st of january, 1970 in milliseconds. What i want to know is, is there a function or possiblitiy to get the current time. if its there, can i get a sample code on how we can use it as an attribute in a node. also do tell me if its possible to extract data from the node that was updated a few hours ago using timestamp function itself</p>
