Dates (Heat Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	DATES	time in milliseconds		Dates define the amount of timeframes and are used to define the day and time for calculating sun angles.	n/a

Notes

• It is recommended to use the Heat Overlay Wizard to generate and edit the dates.
• The sun altitude and sun azimuth are (re)calculated automatically based on the project world location and the date, when the dates of the overlay are modified via the Heat Overlay configuration wizard. They are not automatically recalculated when the dates attribute of the Heat Overlay is modified directly.
• The dates are stored as milliseconds past the defined epoch. Care should be taken when manually adjusting these numbers!
