Wes McKinney commented on ARROW-316:
------------------------------------
[~virtualluke] do you have any documentation about that? The {{date}} command
returns the current system time, which does account for leap seconds. When
there is a leap second, the same second occurs twice
https://access.redhat.com/articles/15145. As far as the actual UNIX timestamps,
my understanding is that they do not include leap seconds.
