[Typo3] Extended Calendar Showing Wrong Dates

[Tim Fink]

Hello,

I am having trouble with events frequently showing up one day early in the 
Extended Calendar. If I enter a "Regular Event" with a start and end date of 
27-8-2005, it shows up incorrectly on the 26th on the upcoming and month 
views. If I enter another on the 17-8-2005, it shows up on the 17th like it 
should.

The hosted server I am using is running these versions:
- Extended Calendar 1.1.3
- TYPO3 3.8.0
- PHP 4.4.0
- Linux Kernel 2.4.20-021stab028.12.777-enterprise

Does anyone have any ideas why?

I am running a copy of this TYPO3 site at home on a Windows machine without 
this problem, even though I am using the same version of the calendar, TYPO3 
and PHP. I don't know much about Linux. Is there possibly a regional setting 
that would effect the date calculations?
