You specify which value you want from the array by using parameters on the web tags for number of days ago, hours ago, and minutes ago. For example, <#RecentOutsideTemp m=1> will give the temperature one minute ago, <#RecentOutsideTemp h=1> will give the temperature one hour ago (as will <#RecentOutsideTemp m=60>), and <#RecentOutsideTemp d=1> will give the temperature one day ago. <#RecentOutsideTemp d=1 h=1 m=1> will give the temperature one day, one hour and one minute ago. All values supplied for parameters must be whole numbers. If you don't supply any parameters, the result is undefined. (Again note that parameters specify time-stamped array element to retrieve based on counting back from current local time so the result for any period when clocks change may not be quite what you anticipated). | You specify which value you want from the array by using parameters on the web tags for number of days ago, hours ago, and minutes ago.

Although 'Apparent Temperature' is not included as a tag, it can be [[FAQ#What_formula_does_Cumulus_use_for_Apparent_Temperature.3F | calculated]] in a script from recent 'outside temperature', 'wind speed', and 'relative humidity' values (using the same time selection for all). | Although 'Apparent Temperature' is not included as a tag, it can be [[FAQ#What_formula_does_Cumulus_use_for_Apparent_Temperature.3F | calculated]] in a script from recent 'outside temperature', 'wind speed', and 'relative humidity' values (using the same time selection for all). | ||
