angleFromHourMinSec function
Constructs an angle from hours, minutes and seconds of time (as opposed to arc).
Implementation
Angle angleFromHourMinSec(int hour, int minute, double second,
[double uncert = 0]) {
final mks = hoursTime.toMks(hour).toDouble() +
minutesTime.toMks(minute).toDouble() +
secondsTime.toMks(second).toDouble();
return Angle.inUnits(mks, Angle.radians, uncert);
}
