What is the C# DateTimeOffset equivalent in Go

问题

我有以下代码，它接受一个字符串作为输入，将其转换为UNIX时间戳。我想在Go中做同样的事情，但我无法识别出相当于Go中DateTimeOffset结构或函数的结构或函数。

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"time"
  6. )
  8. func main() {
  9. 	date := GetUtcTimestampFromAttribute()
  10. 	fmt.Println(date)
  11. 	if date != nil {
  12. 		fmt.Println(ToUnixTimeStamp(*date))
  13. 	}
  14. }
  16. func GetUtcTimestampFromAttribute() *time.Time {
  17. 	ticks := int64(7036640000000)
  18. 	fmt.Println(ticks)
  19. 	return GetUtcTimestampFromTicks(ticks)
  20. }
  22. func GetUtcTimestampFromTicks(ticks int64) *time.Time {
  23. 	fmt.Println(time.Unix(0, ticks))
  24. 	if ticks != 0 {
  25. 		t := time.Unix(0, ticks)
  26. 		return &t
  27. 	} else {
  28. 		return nil
  29. 	}
  30. }
  32. func ToUnixTimeStamp(timeStamp time.Time) int64 {
  33. 	epoch := time.Date(1970, 1, 1, 0, 0, 0, 0, time.UTC)
  34. 	return timeStamp.Sub(epoch).Seconds()
  35. }

例如：

输入：635804753769100000

输出：1444878577

对应的UTC时间：2015年10月15日上午3:09:36 +00:00

请问有人可以帮我找到上述结果的解决方法吗？

谢谢

I have the following code which takes a string as input which is converted into UNIX time stamp. I want to do the same in golang but I am not able to recognize the struct or function which will give an equivalent of DateTimeOffset structure in Go.

  1. class Program
  2. {
  3.     static void Main(string[] args)
  4.     {
  5.         var date = GetUtcTimestampFromAttribute();
  6.         Console.WriteLine(date);
  7.         if (date != null)
  8.         {
  9.             Console.WriteLine(ToUnixTimeStamp(date.Value));
  10.         }
  12.         Console.ReadKey();
  13.     }
  15.     public static DateTimeOffset? GetUtcTimestampFromAttribute()
  16.     {
  17.         var ticks = long.Parse("7036640000000");
  18.         Console.WriteLine(ticks);
  19.         return GetUtcTimestampFromTicks(ticks);
  20.     }
  22.     public static DateTimeOffset? GetUtcTimestampFromTicks(long ticks)
  23.     {
  24.         Console.WriteLine(new DateTimeOffset(ticks, TimeSpan.Zero));
  25.         return ticks != 0 ?
  26.             new DateTimeOffset(ticks, TimeSpan.Zero) :
  27.             (DateTimeOffset?)null;
  28.     }
  30.     public static long ToUnixTimeStamp(DateTimeOffset timeStamp)
  31.     {
  32.         var epoch = new DateTimeOffset(1970, 1, 1, 0, 0, 0, TimeSpan.Zero);
  33.         return Convert.ToInt64((timeStamp - epoch).TotalSeconds);
  34.     }
  35. }

For example:

Input: 635804753769100000

Output: 1444878577

Corresponding Time in UTC : 10/15/2015 3:09:36 AM +00:00

Can someone please help me on a workaround to get the above result.

Thanks

我相信time包拥有你所需的一切，并且在我使用过的所有语言中，它是我认为最好的时间库。示例代码如下：

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"time"
  6. )
  8. func main() {
  10. 	// 这是如何解析一个Unix时间戳
  11. 	t := time.Unix(1444902545, 0)
  13. 	// 获取UTC时间
  14. 	fmt.Println("转换为UTC时间：", t.UTC())
  16. 	// 将其转换为任何时区：FixedZone可以接受UTC偏移和时区名称
  17. 	fmt.Println(t.In(time.FixedZone("IST", 7200)))
  19. }

编辑 将时间对象转换回Unix时间戳很简单：

  1. t.Unix()

或者

  1. t.UnixNano()
英文:

I believe the time package has everything you need and it is IMO the best time library I've worked with in any language. Example:

  1. package main 
  3. import(
  4. 	"fmt"
  5.     "time"
  6. )
  8. func main(){
  10.     // this is how you parse a unix timestamp    
  11.     t := time.Unix(1444902545, 0)
  12.     
  13.     // get the UTC time
  14.     fmt.Println("The time converted to UTC:", t.UTC())
  15.        
  16.     // convert it to any zone: FixedZone can take a utc offset and zone name
  17.     fmt.Println(t.In(time.FixedZone("IST", 7200)))
  19. }

EDIT Converting the time object back to a unix timestamp is simple:

  1. t.Unix()

or

  1. t.UnixNano()

例如，

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"time"
  6. )
  8. func TimeFromTicks(ticks int64) time.Time {
  9. 	base := time.Date(1, 1, 1, 0, 0, 0, 0, time.UTC).Unix()
  10. 	return time.Unix(ticks/10000000+base, ticks%10000000).UTC()
  11. }
  13. func main() {
  14. 	fmt.Println(TimeFromTicks(635804753769100000))
  15. }

输出：

  1. 2015-10-15 03:09:36.0091 +0000 UTC
英文:

For example,

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"time"
  6. )
  8. func TimeFromTicks(ticks int64) time.Time {
  9. 	base := time.Date(1, 1, 1, 0, 0, 0, 0, time.UTC).Unix()
  10. 	return time.Unix(ticks/10000000+base, ticks%10000000).UTC()
  11. }
  13. func main() {
  14. 	fmt.Println(TimeFromTicks(635804753769100000))
  15. }

Output:

  1. 2015-10-15 03:09:36.0091 +0000 UTC
