To parse string to time in golang, must define layout first.
|
||
|
|
|
||
|
|
Read default layouts in [Constants](https://golang.org/pkg/time/#pkg-constants).
|
||
|
|
|
||
|
|
The reference time:
|
||
|
|
|
||
|
|
```txt
|
||
|
|
Mon Jan 2 15:04:05 MST 2006
|
||
|
|
```
|
||
|
|
|
||
|
|
To define your layout, rewrite reference time in your layout.
|
||
|
|
|
||
|
|
Example `Parse`:
|
||
|
|
|
||
|
|
```go
|
||
|
|
layout := "2006-01-02 15:04:05"
|
||
|
|
|
||
|
|
t, err := time.Parse(layout, "2020-06-09 23:04:02")
|
||
|
|
if err != nil {
|
||
|
|
log.Fatal(err)
|
||
|
|
}
|
||
|
|
|
||
|
|
fmt.Println(t)
|
||
|
|
```
|
||
|
|
|
||
|
|
Example `ParseInLocation`:
|
||
|
|
|
||
|
|
```go
|
||
|
|
layout := "2006-01-02 15:04:05"
|
||
|
|
|
||
|
|
loc, err := time.LoadLocation("Asia/Ho_Chi_Minh")
|
||
|
|
if err != nil {
|
||
|
|
log.Fatal(err)
|
||
|
|
}
|
||
|
|
|
||
|
|
t, err := time.ParseInLocation(layout, "2020-06-09 23:04:02", loc)
|
||
|
|
if err != nil {
|
||
|
|
log.Fatal(err)
|
||
|
|
}
|
||
|
|
|
||
|
|
fmt.Println(t)
|
||
|
|
```
|
||
|
|
|
||
|
|
Example `Format` with layout:
|
||
|
|
|
||
|
|
```go
|
||
|
|
now := time.Now()
|
||
|
|
|
||
|
|
layout := "2006-01-02"
|
||
|
|
fmt.Println(now.Format(layout))
|
||
|
|
```
|
||
|
|
|
||
|
|
Example `Format` with layout and location:
|
||
|
|
|
||
|
|
```go
|
||
|
|
loc, err := time.LoadLocation("Asia/Ho_Chi_Minh")
|
||
|
|
if err != nil {
|
||
|
|
return "", err
|
||
|
|
}
|
||
|
|
|
||
|
|
now := time.Now().In(loc)
|
||
|
|
|
||
|
|
layout := "2006-01-02"
|
||
|
|
fmt.Println(now.Format(layout))
|
||
|
|
```
