golang 时间格式化总结

根据字符串创建一个基于当地时区的时间类型

Date.now

 

now := Date.now() 

2019-06-27 10:28:31.282649389 +0800 CST m=+0.000347190

time.Parse

 

before, _:= time.Parse("2006-01-02 15:04:05", "2019-06-26 22:06:00")

结果是 2019-06-26 22:06:00 +0000 UTC

2019-06-26 22:06:00time.ParseInLocation

 

local, _:=time.ParseInLocation("2006-01-02 15:04:05", "2019-06-26 20:00:00", time.Local)
// 2019-06-26 22:06:00 +0800 CST

将当地时区转化为UTC时间

 

// local根据上一步创建的是 2019-06-26 22:06:00 +0800 CST
utcLocal :=local.UTC()

2019-06-26 14:06:00 +0000 UTC

将UTC时间转化为当地时间

 

local2 :=utcLocal.Local()

2019-06-26 22:06:00 +0800 CST
