Cannot access zencart admin

[alluring]

Hi guys, need help here. I was trying to change the timezone in my store and I accidentally saved it as "+" instead of "+8". Now I can't enter my zencart admin and all I see is this error message.

"1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '), '0', 'login.php ', '', '220.255.2.138')' at line 1
in:
[insert into zen_admin_activity_log (access_date, admin_id, page_accessed, page_parameters, ip_address) values (date_add(now(), INTERVAL + HOUR), '0', 'login.php ', '', '220.255.2.138')]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields."

How do I undo this error? Without zencart admin, my store will be suffering badly in terms of reputation. Hope some kind soul can offer some advice asap.

Thanks a million. I'm quite desperate here.

Hi,
I wish I could help you with your problem...but, you might be able to help me? I need to edit my site and I can't remember how to get to the site where I can edit my settings. I put my page up a year ago for show basically and have not had any orders. Could you please help me? I asked for help in forums but nobody has replied.
Thank you so much for your time.

clear your cache for starters.
looks like mySQL is asking you to use phpmyadmin to access the ' admin_activity_log ' table and look for the last log entry and edit the fields as it says above "INTERVAL + HOUR), '0',"to correct the time

in a web browser type http://www.yoursite.com/whatever_you..._admin_folder/ will take you to the admin login page
