AstroTime.jl provides a high-precision, time-scale aware, `DateTime`-like data type which supports

all commonly used astronomical time scales.

## Installation

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

```julia

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

```

## Quickstart

```julia

# Create an Epoch based on the TT (Terrestial Time) scale

tt = TTEpoch("2018-01-01T12:00:00")

# Transform to TAI (International Atomic Time)

tai = TAIEpoch(tt)

# Transform to TDB (Barycentric Dynamical Time)

tdb = TDBEpoch(tai)

# Shift an Epoch by one day

another_day = tt + 1days

```
