Time of day tariff creation methods
Time of year tariffs divide the year into multiple sections (usually seasons), where each section has one or more day types. For example, a four tariff configuration using this method could have Summer and Winter seasons that also use different weekend and weekday tariffs.
Daily tariffs can divide days by day of the week, a weekday, a weekend, or every day, and can specify the time of day. For example, a four tariff configuration could have every day in the year divided into six-hour tariff periods or could have two tariffs for weekends and two tariffs for weekdays.
You can combine these methods if, for example you wanted to create a tariff that applies on Mondays from January 1 to June 30, from 09:00 to 17:00. However, since only one tariff can be applied at any time, you cannot use an everyday or weekday tariff type because you already specified a tariff for the time periods 09:00 to 17:00.
Depending on how you configure the tariffs and the maximum number of tariffs supported by your meter, you may not be able to assign tariffs for the entire year, potentially leaving time gaps that do not have any tariff assigned to them.
