DateTime with Microseconds

DateTime and DateInterval classes with support of microseconds

NOTE! This package not fully tested, so use it with caution.

This small package with two classes just wrapper around built in PHP classes for work with date and time but with support operations with microseconds.


Package use PSR-4 standard, so for using this classes just install package using Composer.

$ composer require oat-sa/lib-tao-dtms
    "require": {
        "oat-sa/lib-tao-dtms": "~0.5"
require 'vendor/autoload.php';

use oat\dtms\DateTime;
use oat\dtms\DateInterval;


After installation you can create DateTime instances with microseconds.

$dt = new DateTime('2015-08-08 10:10:10.123456');
echo $dt->format('Y-m-d H:i:s.u'); // 2015-08-08 10:10:10.123456

Also you can modify DateTime with microseconds. Supported words "microseconds", "microsecond", "micro", "mic".

$dt = new DateTime('2015-08-08 10:10:10.123456');
$dt->modify('123456 micro');
echo $dt->format('u'); // 246912

And of course this package allow usage true ISO8601 format for date intervals with microseconds.

$interval = new DateInterval('PT2.2S');
echo $interval->format('PT%sS'); // PT2.200000S 

Class DateTime support standard methods, such as add, sub, diff, format etc.

For using native DateTime and DateInteval classes together with package use root namespace for it:

$uDateTime = new DateTime(); // DateTime from package
$nativeDateTime = new \DateTime(); // built in DateTime

Note! Current package may work incorrectly with different time zones, so it need extra check and more tests.

If you found error or weird behavior, send me issue report, please.
