Overview

International Atomic Time, the scale atomic clocks keep. The library stores an instant as a TAI Julian Date, so reading an instant in TAI returns the value it already holds.

Examples:

instant = Horologium::Instant.from_julian_date(
  2_443_144.5,
  scale: :tai
)
instant.to(:tai).as(:julian_date) # => 2443144.5

Class Method Summary collapse

.from_reference(value, _precision) ⇒ Horologium::Numeric::TwoPartFloat, Horologium::Numeric::Exact
The value, unchanged: instants are stored in TAI.
.to_reference(value, _precision) ⇒ Horologium::Numeric::TwoPartFloat, Horologium::Numeric::Exact
The value, unchanged: instants are stored in TAI.
