Enum TimeSystem 

pub enum TimeSystem {
    Gps,
    Glo,
    Gal,
    Tai,
    Utc,
    Qzs,
    Bdt,
    Irn,
}

The time system the epoch records are stamped in, from the SP3 %c header (SP3-c/d field 4).

It matters because an SP3 epoch is not a time until the scale is named: IGS products are GPS time, IGLOS products are UTC, and the two differ by the whole leap-second count.

Variants

Gps

GPS time. The default the format assigns when the field is absent or blank.

Glo

GLONASS time, which is UTC(SU) plus three hours and carries leap seconds.

Gal

Galileo system time.

Tai

International Atomic Time.

Utc

Coordinated Universal Time.

Qzs

QZSS time.

Bdt

BeiDou time.

Irn

NavIC (IRNSS) time.

Implementations

impl TimeSystem

pub const fn tai_offset_seconds(self) -> Option<f64>

Seconds to add to an epoch in this system to reach TAI, where that offset is a constant.

None for TimeSystem::Utc and TimeSystem::Glo, whose offset is the leap-second count at the epoch — a property of the date, not of the scale, so it is the caller’s leap-second table to apply and not this type’s to guess.
