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.
