Background Knowledge

I’m trying to determine the difference in minutes between two timestamps. I’m using Pear::Date to do this. The issue comes into play when I noticed that the wrong timezone was being used by Pear::Date, UTC. If I do not use Pear::Date the timezone is set correctly.

I have tried using date_default_timezone_set() and it does set the timezone back, however I feel this shouldn’t be necessary as the default timezone should be used. I have been using date_default_timezone_get() to determine what timezone is being used.

It’s my understanding that Pear::Date uses UTC when it is unable to determine the default timezone. As far as I know I have the default timezone set correctly and with a valid ID (see below). I was able to determine that the timezone changed from my default timezone to UTC after I used Date::setFromDateDiff(). This does not seem right at all.

I have checked the following.

• Pear v1.7.2 stable
• Pear::Date v1.4.7 stable

• php.ini (default timezone) – date.timezone = “Canada/Saskatchewan”
• phpinfo() – Correct configure file being loaded, /var/www/conf/php.ini.
• phpinfo() – Under Date, date/time support is enabled.
• phpinfo() – Default timezone – Canada/Saskatchewan
• phpinfo() – date.timezone - Canada/Saskatchewan / Canada/Saskatchewan

require_once("Date.php");
 
$obFirstDate = new Date('20081014155640');
$obSecondDate = new Date(date("YmdHis",time()));
 
$obDateSpan = new Date_Span();
$obDateSpan->setFromDateDiff($obFirstDate, $obSecondDate);
echo (int)$obDateSpan->toMinutes();
echo "<br />".date_default_timezone_get();

Solution – Unknown

Does anyone have any suggestions where to look or what to do to fix this problem?
