Getdate() function to get date for my timezone

I would love to insert a default value into a column with data type datetime2(7). However, because my website is hosted on a server in a different timezone, the getdate function doesn't work properly. I wonder if there is a solution to this. I have done some research and found two ways. First is to use GetUTCDate() function. However, I would need to do the conversion when I display the information. I am sure my web application is used for only my timezone. So I would like to avoid this. Second way, this is the closest I could get this done by using SwitchOffSet function:

CREATE TABLE [dbo].[Test_Date](
[test_id] [int] NOT NULL,
[test_date] [datetime2](7) NOT NULL
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[Test_Date] ADD  CONSTRAINT [DF_Test_Date_test_date]  DEFAULT (switchoffset(CONVERT([datetimeoffset],getutcdate()),'+13:00')) FOR [test_date]
GO

However, my problem is the +13:00 cause in the next few months, it will be +12:00 cause of the day light saving time change. As a result, I would need to change it every time. Anybody has a solution to this?

Thanks.

SELECT GETDATE() AT TIME ZONE 'UTC' AT TIME ZONE 'Central Standard Time'

You need the first 'AT TIME ZONE UTC' in order to tell the DB what the value currently is in, so it knows how to get to the second given time zone, 'Central Standard Time' in my example.
