Struct GeoLocation 

pub struct GeoLocation {
    pub latitude: f64,
    pub longitude: f64,
    pub elevation: f64,
    pub timezone: Tz,
}

A struct that contains location information such as latitude and longitude required for astronomical calculations. The elevation field may not be used by some calculations and would be ignored if set

Fields

latitude: f64

The latitude in the World Geodetic System, or degrees North of the Equator

longitude: f64

The longitude in the World Geodetic System, or degrees East of the IERS Reference Meridian

elevation: f64

The elevation in meters above sea level

timezone: Tz

The location’s time zone, from chrono_tz

Implementations

impl GeoLocation

pub fn local_mean_time_offset(&self) -> f64

Returns the location’s local mean time offset from UTC in hours. The globe is split into 360°, with 15° per hour of the day. For a local that is at a longitude that is evenly divisible by 15 (longitude % 15 == 0), at solar noon (with adjustment for the equation of time) the sun should be directly overhead, so a user who is 1° west of this will have noon at 4 minutes after standard time noon, and conversely, a user who is 1° east of the 15° longitude will have noon at 11:56 AM. Lakewood, N.J., whose longitude is -74.222, is 0.778 away from the closest multiple of 15 at -75°. This is multiplied by 4 to yield 3 minutes and 10 seconds earlier than standard time. The offset returned does not account for the Daylight saving time offset since this struct is unaware of dates.
