Hi there,

I've downloaded and imported an .ics file from my website, but when I look in my calendar in Outlook the time is wrong by one hour.

I think it might be related to daylight saving time.www.gov.uk/when-do-the-clocks-change

What can be done to resolve this?

Hi Eoin,

Open the .ics file with a text editor, and you'll see the time listed in DTSTART and DTEND, which are always in UTC. Do whatever timezone conversion is needed. If the time is correct in the ICS file then Outlook is messing it up. If the time is wrong then the issue is with the server/website.

If the server/website is wrong, first start by troubleshooting the server - what time does it think it is, and what timezone and rules for DST does it have? If they are fine, then you have to look at what time and timezone, and DST rules PHP thinks it uses. Move onto Joomla with the same questions - what time, timezone and DST rules is it obeying.

If these are correct, then its time (pardon the pun) to look at JEM, but only then.

PS More than you ever wanted to know about ICS format at tools.ietf.org/html/rfc5545, and specifically section 3.8.2

Hi Eoin,

I see that you've thanked me, which I appreciate. Did you locate the source of the problem?

Afraid I haven't had time to look at the moment, but your advice seems solid, so I thanked you for providing me a procedure for following. I'm not entirely sure how to check the date on the server etc., but I will find back and report.

Ok - I just wanted to ensure that you had all the info you needed and were not stuck. Since there are many different servers and admin apps to manage them, your best bet would be to talk with your hosting provider. Joomla's admin settings lets you choose the timezone in Admin | System | Global Configuration | Server | Location Settings.

Hi

I'm seeing the same thing where calendar is 14:00 but ical displays as 15:00.
I have edited the ical with notepad and see that DTSTART:20160625T140000Z so the ical is at 14:00

Is there anything else I can do to fix this as it has been reported by several users on our site..

Cheers
