I believe that the requirement, in the US, for time stamping financial 
transactions is +/- 2 seconds.   Even if a system fails to handle a leap 
second properly, it should still be within specification.

How many systems do not handle leap seconds correctly?  I would expect 
most of the major operating systems, with the possible exception of 
Windows, to handle leap seconds properly.
