Dates (Heat Stress Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	DATES	time in milliseconds		: Dates specify the timeframes (day and time) used to calculate sun angles.	1375444800000

Notes

• It is recommended to use the Heat Stress Overlay Wizard to generate and edit the dates.
• The sun altitude and sun azimuth are automatically recalculated based on project location and date only when using the Heat Stress Overlay configuration wizard, not when modifying the attribute directly.
• The dates are stored as milliseconds past the defined epoch. Care should be taken when manually adjusting these numbers!
