Im not really sure if this is the correct forum so I apologise in advance if its not.

Ive built a site for a friend using concrete5 and hosted by JoneSolutions as per a couple of recommendations on here. Its all been excellent except for the final piece of the puzzle which is using an existing 'add-on' called Upcoming Events to simply produces a list of events from a google calendar.

The add-on itself works but the events are all listed 24 hours after they should be. For example an event listed 17/09/2012 at 4-5pm will show up as 18/09/2012 4-5pm.

Ive set the timezone in the site.php file to be Pacific/Auckland to handle the US hosting. Ive updated the add-on with the same timezone and the google calendar is set to Pacific/Auckland also. The developer hasnt replied at all to my support request so I thought Id ask here.

If I use Australia/Perth I get the correct date and the time is correct when factoring in they are four hours behind. Its correct for Adelaide but not for Melbourne or Sydney. The time is correct (with the delay) but the date is now +24 hours.

I know its a very generic question but is there anything else I need to consider with regards to PHP timezones, hosting in the US and using NZ calendars ?

[e] spelling !

And what is the timezone on the server itself? Is there any configuration you have to set in your script regarding what is the server timezone in addition to the local timezone?

Until now Ive just assumed the server was in the US, so Ive asked them to confirm where it actually is.

Within the add-on there is only the option to set the local timezone, not the server timezone.

If it's not too late... best practice (imo) is to store all date/time's in UTC in your database and adjust the display of the date/time for your users's current timezone in the UI.

This will save you untold trouble down the line.

Ragnor: If it's not too late... best practice (imo) is to store all date/time's in GMT or UTC in your database and adjust the display of the date/time to your users's current timezone in the UI.

QFT... a much better way to go

JonesSolutions have confirmed the server timezone is America/New_York.

I understand the preference to store the dates and times in UTC and updating them on the GUI only but with my friend using google and the add-on only allowing me to update a local timezone I have little to no control over how they are stored.

JoneSolutions say the timezone is set in a serverwide php/ini file. Am I right in thinking there should also be one of those in the site itself which I could set ?
