Astronomical time keeping in Julia

AstroTime.jl provides a high-precision, time-scale aware, DateTime-like data type which supports all commonly used astronomical time scales.


The package can be installed through Julia's package manager:

julia> import Pkg; Pkg.add("AstroTime")


# Create an Epoch based on the TT (Terrestial Time) scale
tt = TTEpoch("2018-01-01T12:00:00")

# Transform to UTC (Universal Time Coordinated)
utc = UTCEpoch(tt)

# Transform to TDB (Barycentric Dynamical Time)
utc = TDBEpoch(utc)

# Shift an Epoch by one day
another_day = tt + 1days
