Function astro::time::delta_t [−] [src]

pub fn delta_t(year: i32, month: u8) -> f64

Computes an approximate value of ΔT for a given year and month

This function approximates ΔT from polynomial expressions using a method different from that given in the Meeus book. The method used is given here; it covers a far wider time range, and is more accurate.
