Problem with ON UPDATE CURRENT_TIMESTAMP

Problem with ON UPDATE CURRENT_TIMESTAMP

Problem with ON UPDATE CURRENT_TIMESTAMP

(OP)
It's supposed to be possible to put a "DEFAULT CURRENT_TIMESTAMP" and/or "ON UPDATE CURRENT_TIMESTAMP" clause on a TIMESTAMP or DATETIME column when creating a table. I'm getting an error on the "ON UPDATE". Is this not possible with MS SQL Server?

CODE --> DDL

CREATE TABLE testTbl (
	id		INT,
	txt		VARCHAR(100),
	ts		TIMESTAMP	DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
	);

CODE --> Error

Msg 156, Level 15, State 1, Line 9
Incorrect syntax near the keyword 'ON'.

I'm an Oracle guy adrift in a SQL Server world.
