When running under Linux (or any other GNU timezone/locale platform) 
then no different than any  other year.  Just ensure you have the 
correct and updated timezone file installed and your system configured 
correctly to pick it up.

And how long ago did you stop beating your wife?

(A question with an inherent assumption that it's affected in the first place.)

OpenSSL code falls back on the c library (ultimately the kernel on many
platforms) so you'll have to consult your C library/OS vendor for more info
and updates.

Offhand, the impact could be a one-hour error in the creation or expiration
dates of certificate data, or the failure of the cache to cross over time
zones at the right moment.  Since OpenSSL attempts to resolve to GMT there
would be a potential one-hour discrepancy between the new changeover
and the historical/anticipated change of date, with possibly no impact
to the resulting gmt conversion whatsoever depending on the c library
implementation, AFAIK.

Of course other things on an unpatched system are likely to fall over first.
