This can also be done through the SSMS GUI.

In that table in SQL Server, specify the default value of that column to be CURRENT_TIMESTAMP. The datatype of that column may be datetime or datetime2.

e.g.

Create Table Student
(
  Name varchar(50),
  DateOfAddmission datetime default CURRENT_TIMESTAMP
);
