How to convert unix timestap to hexadecimal

问题

我有这段C代码，我想要将其翻译成Go语言：

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"time"
  6. )
  8. func main() {
  9. 	started := time.Now()
  10. 	ms := started.UnixNano() / 1000000
  11. 	fmt.Printf("Time: %011x\n", ms)
  12. }

然而，我不知道如何将这个数字转换为十六进制（与我所拥有的C代码的输出相似）。我找到了如何解码十六进制时间戳的方法，可以参考这个问题/答案。有人可以指点我吗？

英文:

I have this snippet of C code that I'm trying to translate to Go:

  1. #include <sys/time.h>
  2. #include <sys/types.h>
  3. #include <inttypes.h>
  4. #include <stdint.h>
  5. #include <stdio.h>
  6. #include <stdlib.h>
  7. #include <string.h>
  8. #include <time.h>
  12. int main()
  13. {
  14.     struct timeval started;
  15.     int64_t ms;
  16.     
  17.     gettimeofday(&started, NULL);
  18.     ms = (int64_t) started.tv_sec * 1000 + started.tv_usec / 1000;
  19.     printf("Time: %011"PRIx64"\n", ms);
  21.     return 0;
  22. }

I've found how to convert unix time to millieseconds by using the below snippet:

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"time"
  6. )
  8. func main() {
  9. 	fmt.Printf("Unix Time in ms: %d \n", time.Now().UnixNano() / 1000000)
  10. }

However I'm having a hard time how to convert that number into hexadecimal (That somewhat resembles the output of the C code that I have.) I did find how to decode the hextime stamp using this questions / answer. Can anyone point me in the right direction?

我已经为您翻译了代码，请查看以下内容：

这应该是正确的解决方案：

  1. package main
  3. import (
  4.     "fmt"
  5.     "time"
  6. )
  8. func main() {
  9.     unix_time_ms := 1589664726314
  10.     fmt.Printf("Hex Unixtime in MS: %x ,should equal 1721f66bd2a\n", unix_time_ms)
  11. }

在C语言中，应该匹配以下代码：

  1. #include <stdio.h>
  2. #include <inttypes.h>
  4. int main()
  5. {
  6.     int64_t unix_time_ms;
  7.     unix_time_ms = 1589664726314;
  8.     
  9.     printf("Hex Unixtime in MS: %011"PRIx64"\n", unix_time_ms);
  11.     return 0;
  12. }

请注意，我只翻译了代码部分，其他内容不包括在内。

英文:

Think this should be the right solution:

  1. package main
  3. import (
  4.     &quot;fmt&quot;
  5.     &quot;time&quot;
  6. )
  8. func main() {
  9.     unix_time_ms := 1589664726314
  10.     fmt.Printf(&quot;Hex Unixtime in MS: %x ,should equal 1721f66bd2a\n&quot;, unix_time_ms)
  11. }

In C it should match this:

  1. int main()
  2. {
  3.     int64_t unix_time_ms;
  4.     unix_time_ms = 1589664726314;
  5.     
  6.     printf(&quot;Hex Unixtime in MS: %011&quot;PRIx64&quot;\n&quot;, unix_time_ms);
  8.     return 0;
  9. }

你可以在Go语言中使用'%XF'来打印十六进制数。就像下面的例子一样：

  1. package main
  3. import (
  4.     "fmt"
  5.     "time"
  6. )
  8. func main() {
  9.     fmt.Printf("Unix Time in ms: %XF \n", time.Now().UnixNano() / 1000000)
  10. }

Playground链接在这里。

英文:

You can use &#39;%XF&#39; to print hexadecimal in goalng. Like the following

  1. package main
  3. import (
  4.     &quot;fmt&quot;
  5.     &quot;time&quot;
  6. )
  8. func main() {
  9.     fmt.Printf(&quot;Unix Time in ms: %XF \n&quot;, time.Now().UnixNano() / 1000000)
  10. }
