_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

```go

package main

import (

	"fmt"

	"os"

	"time"

	"github.com/trstringer/go-systemd-time/pkg/systemdtime"

)

func main() {

	now := time.Now()

	timeFormat := "3:04 PM on January 2, 2006"

	fmt.Printf("Now is %s\n", now.Format(timeFormat))

	adjustedTime, err := systemdtime.AdjustTime(now, "2d")

	if err != nil {

		fmt.Printf("error adjusting time: %v\n", err)

		os.Exit(1)

	}

	fmt.Printf("Adjusted is %s\n", adjustedTime.Format(timeFormat))

	/*

	   Now is 8:38 PM on September 30, 2020

	   Adjusted is 8:38 PM on October 2, 2020

	*/

}

```
