<h1 id="leap-second-handling" class="section-header"><a href="#leap-second-handling">Leap Second Handling</a></h1>
|
||
<p>Since 1960s, the manmade atomic clock has been so accurate that
|
||
it is much more accurate than Earth's own motion.
|
||
It became desirable to define the civil time in terms of the atomic clock,
|
||
but that risks the desynchronization of the civil time from Earth.
|
||
To account for this, the designers of the Coordinated Universal Time (UTC)
|
||
made that the UTC should be kept within 0.9 seconds of the observed Earth-bound time.
|
||
When the mean solar day is longer than the ideal (86,400 seconds),
|
||
the error slowly accumulates and it is necessary to add a <strong>leap second</strong>
|
||
to slow the UTC down a bit.
|
||
(We may also remove a second to speed the UTC up a bit, but it never happened.)
|
||
The leap second, if any, follows 23:59:59 of June 30 or December 31 in the UTC.</p>
|
||
<p>Fast forward to the 21st century,
|
||
we have seen 26 leap seconds from January 1972 to December 2015.
|
||
Yes, 26 seconds. Probably you can read this paragraph within 26 seconds.
|
||
But those 26 seconds, and possibly more in the future, are never predictable,
|
||
and whether to add a leap second or not is known only before 6 months.
|
||
Internet-based clocks (via NTP) do account for known leap seconds,
|
||
but the system API normally doesn't (and often can't, with no network connection)
|
||
and there is no reliable way to retrieve leap second information.</p>
|
||
<p>Chrono does not try to accurately implement leap seconds; it is impossible.
|
||
Rather, <strong>it allows for leap seconds but behaves as if there are <em>no other</em> leap seconds.</strong>
|
||
Various operations will ignore any possible leap second(s)
|
||
except when any of the operands were actually leap seconds.</p>
|
||
<p>If you cannot tolerate this behavior,
|
||
you must use a separate <code>TimeZone</code> for the International Atomic Time (TAI).
|
||
TAI is like UTC but has no leap seconds, and thus slightly differs from UTC.
|
||
Chrono does not yet provide such implementation, but it is planned.</p>
|
||
<h2 id="representing-leap-seconds" class="section-header"><a href="#representing-leap-seconds">Representing Leap Seconds</a></h2>
|
||
<p>The leap second is indicated via fractional seconds more than 1 second.
|
||
This makes possible to treat a leap second as the prior non-leap second
|
||
if you don't care about sub-second accuracy.
|
||
You should use the proper formatting to get the raw leap second.</p>
|
||
<p>All methods accepting fractional seconds will accept such values.</p>

|

<p>Note that the leap second can happen anytime given an appropriate time zone;
|
||
2015-07-01 01:23:60 would be a proper leap second if UTC+01:24 had existed.
|
||
Practically speaking, though, by the time of the first leap second on 1972-06-30,
|
||
every time zone offset around the world has standardized to the 5-minute alignment.</p>

<p>As a concrete example, let's assume that <code>03:00:60</code> and <code>04:00:60</code> are leap seconds.
|
||
In reality, of course, leap seconds are separated by at least 6 months.
|
||
We will also use some intuitive concise notations for the explanation.</p>
|

<p><code>Time + Duration</code>
|

(short for <a href="#method.overflowing_add_signed"><code>NaiveTime::overflowing_add_signed</code></a>):</p>

<li><code>03:00:59 + 1s = 03:01:00</code>.</li>
|
||
<li><code>03:00:60 + 1s = 03:01:00</code>.
|

Note that the sum is identical to the previous.</li>
|

<li><code>03:00:60 + 60s = 03:01:59</code>.</li>
|
||
<li><code>03:00:60 + 61s = 03:02:00</code>.</li>
|
||
<li><code>03:00:60.1 + 0.8s = 03:00:60.9</code>.</li>

</ul>
|

<p><code>Time - Duration</code>

(short for <a href="#method.overflowing_sub_signed"><code>NaiveTime::overflowing_sub_signed</code></a>):</p>

<ul>

<li><code>03:01:00 - 1s = 03:00:59</code>.</li>

|

<li><code>03:01:00 - 03:00:00 = 60s</code>.</li>
|
||
<li><code>03:00:60 - 03:00:00 = 60s</code>.
|

Note that the difference is identical to the previous.</li>
|

<li><code>03:00:60.6 - 03:00:59.4 = 1.2s</code>.</li>

|

<li><code>03:01:00 - 03:00:60.5 = 0.5s</code>.
|

Note that the difference is larger than the previous,
|
||
even though the leap second clearly follows the previous whole second.</li>
|
||
<li><code>04:00:60.9 - 03:00:60.1 = (04:00:60.9 - 04:00:00) + (04:00:00 - 03:01:00) + (03:01:00 - 03:00:60.1) = 60.9s + 3540s + 0.9s = 3601.8s</code>.</li>
|

</ul>
|
||
<p>In general,</p>
|
||
<ul>
|
||
<li>
|
||
<p><code>Time + Duration</code> unconditionally equals to <code>Duration + Time</code>.</p>
|
||
</li>
|
||
<li>
|
||
<p><code>Time - Duration</code> unconditionally equals to <code>Time + (-Duration)</code>.</p>
|
||
</li>
|
||
<li>
|
||
<p><code>Time1 - Time2</code> unconditionally equals to <code>-(Time2 - Time1)</code>.</p>
|
||
</li>
|
||
<li>
|
||
<p>Associativity does not generally hold, because
|
||
<code>(Time + Duration1) - Duration2</code> no longer equals to <code>Time + (Duration1 - Duration2)</code>
|
||
for two positive durations.</p>
|
||
<ul>
|
||
<li>
|
||
<p>As a special case, <code>(Time + Duration) - Duration</code> also does not equal to <code>Time</code>.</p>
|
||
</li>
|
||
<li>
|
||
<p>If you can assume that all durations have the same sign, however,
|
||
then the associativity holds:
|
||
<code>(Time + Duration1) + Duration2</code> equals to <code>Time + (Duration1 + Duration2)</code>
|
||
for two positive durations.</p>
