timestamp problem

[dast]

Im using postgres 7.2 and PHP, all im trying to do is insert a timestamp into the DB, but coming up with this error.

Query failed: ERROR: Bad timestamp external representation '0.78784300 1058879269'

Here is the code:

		  $time = microtime();

		 $sql = "UPDATE tbllogin SET last_loggedin= '$time' WHERE employee_id =$employee_id";
		 $result = pg_query($sql);

Am i doing something stupid here? The last_loggedin field is set to timestamp data type.

Thanks in advance..
