Meter Readings - Which one is day and which is night? + Economy 7 hours

I have an electric meter with a push button to display the day/night readings. It also has an RFI transmitter, so strictly speaking the usage should be sent to you direct. I checked the Bulb “how to” and I think the larger number should be the day rate. Originally I logged them with Bulb as Rate 1 = Day & Rate 2 = Night but I later reasoned there must be much more usage during the day as I have no storage heater etc. I also don’t know the Economy 7 hours for Bulb, is it supported?

The meter says -
Rate 1 = 23594
Rate 2 = 59097
Rate t (total) = 92692

You’ll need to work it out simply by watching which rate increments during the day.
