    DECLARE @sTmp0 nvarchar(4000)

    -- Unix timestamps stored in ULIDs should be UTC...
    DECLARE @bLocal int
    SELECT @bLocal = 0

    EXEC sp_OAMethod @dt, 'SetFromUlid', @success OUT, @bLocal, @ulid

      BEGIN

        PRINT 'ULID was not valid.'
        EXEC @hr = sp_OADestroy @dt
        RETURN
      END

    -- You can now get the date/time in any desired format.
    -- For example:

    EXEC sp_OAMethod @dt, 'GetAsUnixTime', @iTmp0 OUT, @bLocal
    PRINT 'Unix timestamp = ' + @iTmp0

    EXEC sp_OAMethod @dt, 'GetAsRfc822', @sTmp0 OUT, @bLocal
    PRINT 'RFC822 = ' + @sTmp0

    EXEC sp_OAMethod @dt, 'GetAsTimestamp', @sTmp0 OUT, @bLocal
    PRINT 'Timestamp = ' + @sTmp0

    -- Sample output:

    -- Unix timestamp = 1675608861
    -- RFC822 = Sun, 05 Feb 2023 14:54:21 GMT
    -- Timestamp = 2023-02-05T14:54:21Z

    EXEC @hr = sp_OADestroy @dt
