Sir, - Now that Ireland has committed itself to monetary union with our mainland partners, isn't it appropriate for us also to switch to European time? Clearly, it's too late to do anything in 1997; however, I believe that we should be now be preparing for time synchronisation with the mainland by 1999. It would be apt to unite on time and money in the same year. Yours, etc., Vincent MacCarthy,
