Detailed Description

Provide script API for Stellarium global functions.

Public slots in this class may be used in Stellarium scripts, and are accessed as member function to the "core" scripting object. Module-specific functions, such as setting and clearing of display flags (e.g. LandscapeMgr::setFlagAtmosphere) can be accessed directly via the scripting object with the class name, e.g. by using the scripting command: LandscapeMgr.setFlagAtmosphere(true);

two letter language code, e.g. "en", or "de".

void StelMainScriptAPI::setDate	(	const QString &	dt,
		const QString &	spec = "utc"
	)			[slot]

set the date in ISO format, e.g.

"2008-03-24T13:21:01"

Parameters:

	dt	the date string to use. Formats: ISO, e.g. "2008-03-24T13:21:01" "now" (set sim time to real time) relative, e.g. "+ 4 days", "-2 weeks". can use these units: seconds, minutes, hours, days, weeks, months, years. You may also append " sidereal" to use sidereal days and so on. You can also use "now" at the start. For example: "now + 3 hours sidereal" Note: you must use the plural all the time, even when the number of the unit is 1. i.e. use "+ 1 days" not "+1 day". Note: when sidereal time is used, the length of time for each unit is dependent on the current planet. By contrast when sidereal timeis not specified (i.e. solar time is used) the value is conventional - i.e. 1 day means 1 Earth Solar day.
	spec	"local" or "utc" - only has an effect when the ISO date type is used.
