Given 𝑛, solves for 𝑥 in the equation

1970 + 𝑛 milliseconds = 𝑥

Usage

``` USAGE: unmillis

ARGS: A timestamp formulated as the number of milliseconds since "1970-01- 01T00:00:00+00:00". • Trailing and leading garbage is thrown away, i.e. • 1 hello there, 1, and "1", would all be interpreted as 1. • Negative numbers are fine, positive numbers are ok too, both have some limitations: • We can't construct datetimes outside the range of (-262144-01- 01T00:00:00Z, +262143-12-31T23:59:59.999999999Z), so • we only accept input values in the range of (-8334632851200000, 8210298412799999)
