Enum TimeScale

#[non_exhaustive]
pub enum TimeScale { TAI, TT, ET, TDB, UTC, GPST, GST, BDT, QZSST, }
Expand description

Enum of the different time systems available

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

TAI

TAI is the representation of an Epoch internally

§

TT

Terrestrial Time (TT) (previously called Terrestrial Dynamical Time (TDT))

§

ET

Ephemeris Time as defined by SPICE (slightly different from true TDB)

§

TDB

Dynamic Barycentric Time (TDB) (higher fidelity SPICE ephemeris time)

§

UTC

Universal Coordinated Time

§

GPST

GPS Time scale whose reference epoch is UTC midnight between 05 January and 06 January 1980; cf. https://gssc.esa.int/navipedia/index.php/Time_References_in_GNSS#GPS_Time_.28GPST.29. |UTC - TAI| = 19 Leap Seconds on that day.

§

GST

Galileo Time scale

§

BDT

BeiDou Time scale

§

QZSST

QZSS Time scale has the same properties as GPST but with dedicated clocks
