Just to clarify, what diat150 showing is a script.

There is scripting and there is expression language.

A quick overview can be found [here](http://www.inductiveautomation.com/support/usermanuals/ignition/index.html?about_scripting.htm) in the manual. 🙂

Personally, I prefer using a transaction group for scheduled items, but there are plenty of way to go about it.
