Assignment 3 part 1: "The right time"
Note:
	1: DO NOT use "print" function, it will block the code, 
		use "logger.info()" instead.
	2: ob is a python list with the following items:
		0: hour (0-23)
		1: min (0-59)
		2: weekday (0-7, 0 is Monday)
		3: outdoor air temperature (C)
		4: outdoor air RH (%)
		5: diffuse dolar radiation (W/m2)
		6: direct solar radiation (W/m2)
		7-16: IAT of 10 zones (C)
		17-26: IAT cooling setpoint of 10 zones (C)
		27-36: PMV of 10 zones (-999 if no occupied)
		37: DX heating coil electric demand (W)
		38: HVAC total electric demand (W)
