Date

Date is a 1 date package based on the time wrapper. With this package, you can quickly create a date, get the timestamp, milliseconds, and most important date formatting, and you can continue to use all the functions under the time package (except time.Foramt (string). You can quickly create an Date object by:

Now() WithTime(t time.Time) WithTimestamp(timestamp int64) WithMillisecond(millisecond int64) WithDate(year, month, date, hour, minute, second int)

Note: You can get it via ES29en. Format(String... bool) method to format the date, the date format is in accordance with the Java style, without the Golang unconventional formatting method, which adds great convenience to our use of date format, the following question Java date format reference table:

Using Date

// get date
d:=date.Now()
//d:=date.WithTime(time.Now())
//d:=date.WithTimestamp(1586448000)
//d:=date.WithMillisecond(1586448000000)
//d:=date.WithDate(2020,04,29,0,0,0)
// get milliseconds
//milliseconds:=date.Millisecond()
// get timestamp
//timestamp:=date.Timestamp()
// date format
ret,err:=d.Format("yyyy-MM-dd HH:mm:ss EEEE",true)
if err!=nil{
  log.Fatalln(err)
}
fmt.Println(ret)

G: Reserved fields. Formatting is not supported Year: When the consecutive number of y is less than 4, the year after the abbreviation will be displayed.
