Convert UTC Milliseconds to DATETIME in SQL server

Question

I want to convert UTC milliseconds to DateTime in SQL server.

This can easily be done in C# by following code:

DateTime startDate = new DateTime(1970         


        

Answer 1

Below the function that converts milliseconds to datetime

IF object_id('dbo.toDbTimeMSC', 'FN') IS NOT NULL DROP FUNCTION dbo.toDbTimeMSC
GO
CREATE FUNCTION [dbo].[toDbTimeMSC] (@unixTimeMSC BIGINT) RETURNS DATETIME
BEGIN
    RETURN DATEADD(MILLISECOND, @unixTimeMSC % 1000, DATEADD(SECOND, @unixTimeMSC / 1000, '19700101'))
END
GO

-- select dbo.toDbTimeMSC(1348203320000)
