[RESOLVED] How is a DateTime object created?

cupboy

The manual is incorrect. Copying and pasting their example results in some sort of timezone error. I am in the Mountain Time Zone. Maybe I could put it in if I knew what to put there, but really I just want the computer time. I don't care about the zone at all. The purpose of the code is to obtain yesterday's date. Sounds simple enough doesn't it?

<?php
try {
    $date = new DateTime('2000-01-01');
} catch (Exception $e) {
    echo $e->getMessage();
    exit(1);
}

echo $date->format('Y-m-d');
/*

PHP document: http://us2.php.net/manual/en/datetime.construct.php


DateTime::__construct() [datetime.--construct]: It is not safe to rely on
the system's timezone settings. You are *required* to use the 
date.timezone setting or the date_default_timezone_set() function. 
In case you used any of those methods and you are still getting this
warning, you most likely misspelled the timezone identifier. We selected
'America/New_York' for '-4.0/DST' instead

Not for me; I copied your code and it ran without errors, producing "2000-01-01." Thus, the manual is correct; what is likely incorrect, however, is your PHP configuration. Did you actually read the error message? If so, can you paste it here for us to see?

Did you try reading the [man]timezones[/man] section in the PHP manual?

Okay, well since the other millions of users of PHP do often care about the time zone, so does PHP. Thus the numerous warnings all over the manual, example code, error messages, etc. warning you that you must correctly configure PHP to define the default timezone.

Then why not just do:

echo date('Y-m-d', strtotime('yesterday'));

...And what timezone does it think it's in?

I like that solution. That's what I will use. Thanks.
