Closed huayi closed 10 months ago

huayi commented 11 months ago

my local time is Asia/Shanghai my struct is:

type LogAccess struct {
    Id       string        `json:"id" xorm:"pk"`
    Username string        `json:"username"`
    AccessAt carbon.Carbon `json:"access_at"`
}

use xorm get AccessAt is a UTC time I changed AccessAt type to time.Time, I get a CST time What should I do to get a CST time

complete code:

    AccessAt carbon.Carbon `json:"access_at"`
    LogoutAt time.Time     `json:"logout_at"`
}

func TestGet(t *testing.T) {
    var err error

    db.ShowSQL(true)
    db.DatabaseTZ = time.Local

    acc := &LogAccess{}
    db.ID("1").Get(acc)
    fmt.Println("carbon time:", acc.AccessAt)
    fmt.Println("carbon loc: ", acc.AccessAt.Location())
    fmt.Println("time.Time:", acc.LogoutAt)
}

print:

Thank you. This method is indeed effective. In fact, I want it to default to using the local time zone. I think it would be better if it were set to local time by default in database function func (c *Carbon) Scan(v interface{}). Thank you again.
