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.
