在golang中将datetimeoffset转换为datetime？

I have problem with converting a datetimeoffset to datetime. I have tried to insert into my database using postman with method post in body. But the result is EXEC SMSBlast2Procedure '9', '087871723282', 'adsbjkadhdhad', '0001-01-01 00:00:00', '0001-01-01 00:00:00' , 'asjdasjgdjasgdjsad', '2019-02-24 08:17:54' , where in postman I am inputting like picture below :

respon json like picture below :

but when I check in console result WillBeSentDate is 0001-01-01 00:00:00 and 0001-01-01 00:00:00, why ?

Here my code to datetimeoffset to datetime.

    json.NewDecoder(r.Body).Decode(&smsblats)

    var count int64 = 0
    db.Debug().Table("SMSBlast2").Count(&count)
    count++
    fmt.Println(count)

   formatWill, _ := time.Parse(time.RFC3339, smsblats.WillBeSentDate.String())
   formatSent, _ := time.Parse(time.RFC3339, smsblats.SentDate.String())


    db.Debug().Raw("EXEC SMSBlast2Procedure ?, ?, ?, ?, ? , ?, ?",
        count,
        smsblats.MobilePhone,
        smsblats.Output,
        formatWill,
        formatSent,
        smsblats.Status,
        time.Now()).Scan(smsblats)
    w.Header().Set("Content-Type", "application/json")
    w.Header().Set("Response-Code", "00")
    w.Header().Set("Response-Desc", "Success")
    json.NewEncoder(w).Encode(smsblats)

What wrong with my code? The error says

Error converting data type datetimeoffset to datetime

I'm using SQL Server for database, a stored procedure like this:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[SMSBlast2Procedure]
    (@sequenceid INT,
     @mobilephone VARCHAR(20),
     @output VARCHAR(20),
     @willbesentdate DATETIME,
     @sentdate DATETIME, 
     @status VARCHAR(60),
     @dtmupd DATETIME)
AS
    INSERT INTO SMSBlast2 (SequenceID, MobilePhone, Output, WillBeSentDate, SentDate, Status, DtmUpd) 
    VALUES (@sequenceid, @mobilephone, @output, @willbesentdate, @sentdate, @status, @dtmupd)
