How to get hours difference between two dates
问题
我第一次在Go上工作，这种情况下我有一个以UTC格式表示的字符串，我想知道如何计算我的日期和当前时间之间的小时差。这是我的当前字符串：
v := "2014-05-03 20:57 UTC"
英文:
I'm working for first time on Go, in this case i have a string on UTC format, I would like to know, how can I get the difference in hours between my date and the time now.
This is my current string
v := "2014-05-03 20:57 UTC"

使用time.Parse和time.Since函数进行时间解析和计算时间间隔：
package mainimport ("fmt""time")const (// 参考 http://golang.org/pkg/time/#ParsetimeFormat = "2006-01-02 15:04 MST")func main() {v := "2014-05-03 20:57 UTC"then, err := time.Parse(timeFormat, v)if err != nil {fmt.Println(err)return}duration := time.Since(then)fmt.Println(duration.Hours())}
英文:
Use time.Parse and time.Since:
package mainimport ("fmt""time")const (// See http://golang.org/pkg/time/#ParsetimeFormat = "2006-01-02 15:04 MST")func main() {v := "2014-05-03 20:57 UTC"then, err := time.Parse(timeFormat, v)if err != nil {fmt.Println(err)return}duration := time.Since(then)fmt.Println(duration.Hours())}

请看一下time包。
package mainimport "fmt"import "time"func main() {a, err := time.Parse("2006-01-02 15:04 MST", "2014-05-03 20:57 UTC")if err != nil {// ...return}delta := time.Now().Sub(a)fmt.Println(delta.Hours())}
英文:
Have a look at the time package.
package mainimport "fmt"import "time"func main() {a, err := time.Parse("2006-01-02 15:04 MST", "2014-05-03 20:57 UTC")if err != nil {// ...return}delta := time.Now().Sub(a)fmt.Println(delta.Hours())}
