Overview

Package date provides time.Time derivatives that conform to the Swagger.io (https://swagger.io/) defined date formats: Date and DateTime. Both types may, in most cases, be used in lieu of time.Time types. And both convert to time.Time through a ToTime method.

Functions

func ParseTime

func ParseTime(format string, t string) (d time.Time, err error)

ParseTime to parse Time string to specified format.

Example
d, _ := ParseTime(rfc3339, "2001-02-03T04:05:06Z")
fmt.Println(d)
Output:

2001-02-03 04:05:06 +0000 UTC

func UnixEpoch

func UnixEpoch() time.Time

UnixEpoch retreives the moment considered the Unix Epoch. I.e. The time represented by '0'

Types

type Date

type Date struct {
	time.Time
}

Date defines a type similar to time.Time but assumes a layout of RFC3339 full-date (i.e., 2006-01-02).

Example
d, err := ParseDate("2001-02-03")
if err != nil {
	fmt.Println(err)
}

t, err := time.Parse(time.RFC3339, "2001-02-04T00:00:00Z")
if err != nil {
	fmt.Println(err)
}

// Date acts as time.Time when the receiver
if d.Before(t) {
	fmt.Printf("Before ")
} else {
	fmt.Printf("After ")
}

// Convert Date when needing a time.Time
if t.After(d.ToTime()) {
	fmt.Printf("After")
} else {
	fmt.Printf("Before")
}
Output:

Before After

func ParseDate

func ParseDate(date string) (d Date, err error)

	fmt.Println(err)
}
t, err := d.MarshalBinary()
if err != nil {
