It does if you copy it to the url. This is a UT limitation, it doesn't handle links with () correctly.

Samples from this link:

BEGIN
   WAITFOR TIME '22:20'
   EXECUTE update_all_stats
END

This example shows how a local variable can be used with the WAITFOR DELAY option. A stored procedure is created to wait for a variable amount of time and then returns information to the user as to the number of hours, minutes, and seconds that have elapsed.

CREATE PROCEDURE time_delay @@DELAYLENGTH char(9)
AS
DECLARE @@RETURNINFO varchar(255)
BEGIN
   WAITFOR DELAY @@DELAYLENGTH
   SELECT @@RETURNINFO = 'A total time of ' + 
                  SUBSTRING(@@DELAYLENGTH, 1, 3) +
                  ' hours, ' +
                  SUBSTRING(@@DELAYLENGTH, 5, 2) + 
                  ' minutes, and ' +
                  SUBSTRING(@@DELAYLENGTH, 8, 2) + 
                  ' seconds, ' +
                  'has elapsed! Your time is up.'
   PRINT @@RETURNINFO
END
GO
-- This next statement executes the time_delay procedure.
EXEC time_delay '000:00:10'
GO
