// Node for Node-Red that humalizes a timespan msg.payload.[] //TODO whould this be extended to work on Date objects as well and if so how?
// It is helpful when working with ui things that informs users of time since last operation etc.

// copy "this" object in case we need it in context of callbacks of other functions.
