Can you suggest how schedule a Process?

Question

Hi, 
 
 I'm trying to schedule a process using start node. Below is the screen shot.

If I use pp!timezone I'm getting below. 
 Problem: An error has occurred in evaluation of an expression for a Start Event. Details: ERROR:EVAL:@reason=Domain pp is valid only in execution Recommended Action: Examine and correct the expressions on the Start Event's Event Properties. 
 
 If I'm using pm!timezone I'm getting a problem. The clients are at US and I'm working from India. If schedule 1 AM it is not executing correctly. 
 I want to schedule a process at 1 AM at US time zone. 
 How to schedule it. Please suggest.

The pattern I most commonly settle on for this is to allow the process to be launched anyway (using the basic setup you have pictured already), then immediately after the start node, have an XOR node that checks whether the instance's start time matches the desired launch time, and if not, exit immediately.
