如何通过ORM将字符串解析为Time＆rangeto Date

Problem is i cant filter by date range to date. It gives me zero data. But i have many data at 2019/5/7

timeT := "2019-5-8"
startT, err := time.Parse(time.RFC3339, timeT)

xxx := now.New(startT).BeginningOfMonth()
yyy := now.New(startT).EndOfMonth()

_, err = o.QueryTable("BillDetail").Filter("OriginalID", id).Filter("Date", xxx).Filter("Date", yyy).All(&bills)

    if err != nil {
    return nil, err
}

return bills, err

I used

"time"

"github.com/jinzhu/now"

"github.com/astaxie/beego/orm"

I used debug and i found this output on console

[ORM]2019/05/08 15:12:22  -[Queries/default] - [  OK /    db.Query /    16.9ms] - [SELECT T0.`i_d`, T0.`date`, T0.`name`, T0.`original_i_d`, T0.`value` FROM `bill_detail` T0 WHERE T0.`original_i_d` = ? AND T0.`date` = ? AND T0.`date` = ? ] - `6`, `0001-01-01 08:00:00`, `0001-01-01 08:00:00`

Pay your attention here

`0001-01-01 08:00:00`, `0001-01-01 08:00:00`
