|
|||
|
|
<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.

<p>If you can assume that all durations have the same sign, however,

<h2>Search Tricks</h2>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Prefix searches with a type followed by a colon (e.g.
|
|||
|
|
<code>fn:</code>) to restrict the search to a given type.
|
|||
|
|
</p>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Accepted types are: <code>fn</code>, <code>mod</code>,
|
|||
|
|
<code>struct</code>, <code>enum</code>,
|
|||
|
|
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
|||
|
|
and <code>const</code>.
|
|||
|
|
</p>
|
|||
|
|
|
|||
|
|
<p>
|
|||
|
|
Search functions by type signature (e.g.
|
|||
|
|
<code>vec -> usize</code> or <code>* -> vec</code>)
|
|||
|
|
