A bit of a compilation of other opinions with no attempt at analysis or conclusion.
If folks are poking at date-time code to support another Era, announced with
only a few months notice (like some other events), and can finish within a few
months, adding support for DST at the same time using existing tested
mechanisms, should not add significantly to the dev or QA effort, or increase
the project time frame.
The possibilities for those who choose to reinvent the wheel (badly) are
unlimited in every sense.

If double DST was applied, would these people just be working two hours longer,
with less time for social or leisure viewing?
Is the culture such that these workers would not be at home watching the
Olympics in any case, or would most or some be watching it in bars with their
boss and colleagues after dark?
So who would have time to attend events, or are companies expected to buy blocks
of discounted tickets, and allow, encourage, or compel workers and/or their
families to attend?

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
