# Trick Question: How Many Seconds Are In A Year

TODO: Pull subtitle into page object pre_full_default_section

A year with a positive Leap Second is just slighly longer^3^^.

Of course, Leap Seconds can happen on Leap Years too. So, based on our current system of time^4^^, a year can have one of six possible total seconds.

Trick Question: How Many Seconds Are In A Year

Time is weird. Or, if you prefer, wibbly-wobbly^1^^.

Take someone who lives on a border between time zones
and has a five minute commute. Separate clocks at home
and the office show they make it in before waking up
and that it takes two hours longer to trek home than
it did to come in.

Weird.

A more subtle strangeness is the Leap Second^2^^.

Like the days we add for Leap Years, these seconds
keep our clocks and calendars from drifting away from
their proper seasons. The expected math class answer
for determining how many seconds there are in a year
looks like this:

-- pre

365 days * 24 hr * 60 min * 60 sec = 31,536,000 seconds

-- p

A year with a positive Leap Second is just slighly longer^3^^.

-- pre

365 days * 24 hr * 60 min * 60 sec + 1 Leap Sec = 31,536,001 seconds

-- p

Notice the explicit use of "positive" above.
That's required since Lead Seconds can, in theory,
be negative.

-- pre

365 days * 24 hr * 60 min * 60 sec - 1 Leap Sec = 31,535,999 seconds

-- p

Of course, Leap Seconds can happen on Leap Years too.
So, based on our current system of time^4^^, a year can
have one of six possible total seconds.

Our global time keepers came up with the Leap Second
in 1972. Since then, 25 have been added.  All of the
"positive" variety. And, we're ready for another
one^5^^. This June will be one second longer
than last.

Wibbly-wobbly indeed.

Season three, episode ten of the modern Doctor
Who is titled "Blink". It's a masterpiece.
It's also where
from. If you've not yet tuned into Doctor Who, do
yourself a favor and start from the first episode of
the modern reboot.

To quote the <<link|Wikipedia entry for Leap Second|http://en.wikipedia.org/wiki/Leap_second>>:
A leap second is a one-second adjustment that is
occasionally applied to Coordinated Universal Time (UTC)
in order to keep its time of day close to the mean
solar time.

Without such a correction, time reckoned by Earth's
rotation drifts away from atomic time because of
irregularities in the Earth's rate of rotation.

I trust some clever, smart-ass student will get the
"How many seconds in a year" question and use a Leap
Second in the calculation to see if they can argue the point.

Anyone else remember when, in 1998, Swatch tried to
redefine time with their '.beats' Internet Time?
Saying: "Internet Time exists so that we do not have
to think about timezones. For example, if a
New York web-supporter makes a date for a chat
with a cyber friend in Rome, they can simply agree
to meet at an "@ time" - because internet time is
the same all over the world.""

I was a little surprised that
I haven't heard it mentioned since '98.

from the International Earth Rotation And Reference
Systems Service. It contains the line, "To authorities
responsible for the measurement and distribution of time."
That's just begging to be the opening of a sci-fi novel.
