Thank you Tom. Very informative, sadly no simple answer to overcome the shortcoming. After move, downsizing and age I imposed on my self a buy stop that I keep braking. I did buy this year two 53132A's mainly because of the RS232 interface. Before I had excellent results with a combination

Hi all, So I'm doing the typical Wednesday thing you might do, that is writing a small script for checking the SHA1 checksum in leap-seconds.list files. I came up with [1] which produces output [2]. For the Paris Observatory and USNO files my program agrees with the SHA1s in the files. For the
