I am trying to write a statment using current_timezone that is dependant on a location. We are a transportation company. we in CST timezone. When i deliver to the West cost, our communications units show central time 6am cst. I have the appt time set for 6am PST. when the driver arrives at customer at 6am PST, the communications unit shows 8am. I would like to write the SQL to show the time difference based on the location of the delivery.
