<para>
|
|
The <classname>DateTimeImmutable</classname> and related classes allow you
|
|
represent date/time information. The objects can be created by passing in a
|
|
string presentation of date/time information, or from the current system's
|
|
time.
|
|
</para>
|
|
<para>
|
|
A rich set of methods is supplied to modify and format this information
|
|
as well, including handling timezones and DST transitions.

|
The date/time features in PHP implements the ISO 8601 calendar, which is a
|
|
<link xlink:href="&url.proleptic-gregorian-calendar;">proleptic Gregorian
|
|
calendar</link> which implements the current leap-day rules from before the
|
|
Gregorian calendar was in place, and also includes the year
|
|
<literal>0</literal> as the year number in between <literal>-1
|
|
BCE</literal> and <literal>1 CE</literal>. Leap seconds are not supported.
|
|
</para>
|
|
<para>
|
|
The date and time information is internally stored as a 64-bit number so
|
|
all conceivably useful dates (including negative years) are supported. The
|
|
range is from about 292 billion years in the past to the same in the
|
|
future.
