工具方法

https://godoc.org/github.com/gogf/gf/os/gtime

方法比较简单,比较常用的是以下几个方法; 1. Second用于获得当前时间戳,MillisecondMicrosecondNanosecond用于获得当前的毫秒、微秒和纳秒值; 2. DateDatetime用于获得当前日期及当前日期时间; 3. SetTimeZone用于设置当前进程的全局时区; 4. 其他方法说明请查看接口文档;

示例1,基本使用

package main

import (
    "fmt"
    "github.com/gogf/gf/os/gtime"
)

func main() {
    fmt.Println("Date       :", gtime.Date())
    fmt.Println("Datetime   :", gtime.Datetime())
    fmt.Println("Second     :", gtime.Second())
    fmt.Println("Millisecond:", gtime.Millisecond())
    fmt.Println("Microsecond:", gtime.Microsecond())
    fmt.Println("Nanosecond :", gtime.Nanosecond())
}

执行后,输出结果为:

Date       : 2018-07-22
Datetime   : 2018-07-22 11:52:22
Second     : 1532231542
Millisecond: 1532231542688
Microsecond: 1532231542688688
Nanosecond : 1532231542688690259

示例2,设置时区

package main

import (
    "fmt"
    "github.com/gogf/gf/os/gtime"
    "time"
)

func main() {
    // 先使用标准库打印当前时间
    fmt.Println(time.Now().String())
    // 设置进程全局时区
    err := gtime.SetTimeZone("Asia/Tokyo")
    if err != nil {
        panic(err)
    }
    // 使用gtime获取当前时间
    fmt.Println(gtime.Now().String())
    // 使用标准库获取当前时间
    fmt.Println(time.Now().String())
}

执行后,输出结果为:

2018-11-21 22:50:56.723429 +0800 CST m=+0.000649366
2018-11-21 23:50:56
2018-11-21 23:50:56.723832 +0900 JST m=+0.001052780

示例3,StrToTime

gtime支持常见的时间字符串解析,生成gtime.Time对象,常见的时间字符串如下:

"2017-12-14 04:51:34 +0805 LMT",
"2017-12-14 04:51:34 +0805 LMT",
"2006-01-02T15:04:05Z07:00",
"2014-01-17T01:19:15+08:00",
"2018-02-09T20:46:17.897Z",
"2018-02-09 20:46:17.897",
"2018-02-09T20:46:17Z",
"2018-02-09 20:46:17",
"2018/10/31 - 16:38:46"
"2018-02-09",
"2018.02.09",

01-Nov-2018 11:50:28
01/Nov/2018 11:50:28
01.Nov.2018 11:50:28
01.Nov.2018:11:50:28
日期连接符号支持'-'、'/'、'.'

使用示例:

package main

import (
	"fmt"
	"github.com/gogf/gf/os/glog"
	"github.com/gogf/gf/os/gtime"
	"time"
)

func main() {
	array := []string{
		"2017-12-14 04:51:34 +0805 LMT",
		"2006-01-02T15:04:05Z07:00",
		"2014-01-17T01:19:15+08:00",
		"2018-02-09T20:46:17.897Z",
		"2018-02-09 20:46:17.897",
		"2018-02-09T20:46:17Z",
		"2018-02-09 20:46:17",
		"2018.02.09 20:46:17",
		"2018-02-09",
		"2017/12/14 04:51:34 +0805 LMT",
		"2018/02/09 12:00:15",
		"01/Nov/2018:13:28:13 +0800",
		"01-Nov-2018 11:50:28 +0805 LMT",
		"01-Nov-2018T15:04:05Z07:00",
		"01-Nov-2018T01:19:15+08:00",
		"01-Nov-2018 11:50:28 +0805 LMT",
		"01/Nov/2018 11:50:28",
		"01/Nov/2018:11:50:28",
		"01.Nov.2018:11:50:28",
		"01/Nov/2018",
	}
	cstLocal, _ := time.LoadLocation("Asia/Shanghai")
	for _, s := range array {
		if t, err := gtime.StrToTime(s); err == nil {
			fmt.Println(s)
			fmt.Println(t.UTC().String())
			fmt.Println(t.In(cstLocal).String())
		} else {
			glog.Error(s, err)
		}
		fmt.Println()
	}
}

在这个示例中,将部分时间格式串使用StrToTime方法转换为gtime.Time对象,并输出该事件的UTC时间和CST时间(上海时区时间)。 执行后,输出结果为:

2017-12-14 04:51:34 +0805 LMT
2017-12-13 20:46:34
2017-12-14 04:46:34 +0800 CST
