Cronjob trouble after changing timezone

Question

After made that: How to change Magento timezone

My magento regional time was Europe/Paris but I tried to change to Europe/Budapest (both are the same..)

AOE Scheduler says

Last heartbeat is older than one hour. Please check your settings and your configuration!

What I have made:

Mage.php (before)

            date_default_timezone_set('UTC');

Mage.php (after)

            date_default_timezone_set('Europe/Budapest');

config.xml (before)

        <locale>
            <code>en_US</code>
            <timezone>America/Los_Angeles</timezone>
        </locale>

config.xml (after)

        <locale>
            <code>en_US</code>
            <timezone>Europe/Budapest</timezone>
        </locale>

I tried to

1. Disable all schedules and remove programmed
2. Disable cron job system
3. Enable cron job system again
4. Enable all schedules and re build programs.

But the problem keeps :/

Is like the cron job hour is advanced (real hour 11:36 in Spain):

Sugestions? Thanks!!

Answer 1

Problem solved

Do NOT change Mage.php file, only config.xml and cron jobs will work fine at time.

Disable all jobs and remove scheduled taks, enable again and all wil be synced.
