 _Go implementation of systemd time (`man systemd.time`)_
 
-In command line applications, it is convenient to use the notation since `-1day`, or in `5 hours`. This package takes that string (using systemd time specs) and converts it into `time.Duration`. There is also a helper function that can take the raw string time adjustment and a `time.Time` (or `nil` for `time.Now()`) object and apply the adjustment to immutably. See [below for usage](#usage).
