Directive Local Value Master Value
date.timezone Europe/Berlin no value
is the default configuration of the php installation
It is also the standard configuration for all shared hosting providers. If you would be rigth, that this configuration cause the problem, yout component would not run on any shared host.
But, honestly, I don't believe that that is the reaseon.
Your component jevents 1.5.4a (b1785) is still working very well, with on the same server.
I think it should be not so hard to compare what has been changed from Version 1.5.4a to Version 2
Thank you very much in advance for your support.
