PEAR is a framework and distribution system for reusable PHP components.

How we get PEAR packages with php files?

Add block of code to the php file….

<?php
// include PEAR class
include (“Date.php”);

// initialize Date object
$d = new Date(“1981-08-07 01:30:11”);

// retrieve date to display
echo $d->getDate();

// retrieve date as formatted string
echo $d->format(“%A, %d %B %Y %T”);

?>

Output:
1981-08-07 01:30:11
Friday, 07 August 1981 01:30:11

Converting between time zones

<?php
// include class
include (“Date.php”);

// initialize object
$d = new Date(“1981-08-07 10:36:27”);

// set local time zone
$d->setTZByID(“GMT”);

// convert to foreign time zone
$d->convertTZByID(“IST”);

// retrieve converted date/time
echo $d->format(“%A, %d %B %Y %T”);
?>

Output:
Thursday, 07 August 1981 16:06:27

Calculating GMT offsets

<?php
// include class
include (“Date.php”);

// initialize object
$d = new Date(“2006-08-08 10:26:27”);

// set local time zone
$d->setTZByID(“PST”);

// get raw offset from GMT, in msec
echo $d->tz->getRawOffset();
?>

Adding and subtracting timespans

<?php
// include class
include (“Date.php”);

// initialize object
$d = new Date(“1951-09-13 16:55:11”);

// add 01:20 to it
$d->addSpan(new Date_Span(“0,1,20,0”));

// subtract 00:05 from it
$d->subtractSpan(new Date_Span(“0,0,5,0”));

// retrieve date as formatted string
echo $d->format(“%A, %d %B %Y %T”);
?>

PHP have rich library to manage “Daylight saving time”… we can use PEAR for DST

United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November.
