[Plugin: Events Manager] Daylight Saving Time problem

btw, @ianbutty, make sure you haven’t got a ical template overriding the default, maybe my fixes aren’t being applied to your site.

Well, here we are:

I am using #_EVENTGCALURL. My WordPress install is set to a city in my timezone.

Today is the day before daylight savings time. Tomorrow we “spring ahead” one hour.

If today I “add to my google calendar” an event happening at 10:00 am today, all is good.

If today I “add to my google calendar” an event happening at 10:00 am tomorrow (which is after DST has kicked in), the event shows up as 11:00 am.

The same thing happens with ical.

Tomorrow I will have to see whether events on tomorrow’s google calendar will “heal” themselves overnight (i.e. what appears incorrectly today as 11:00 am Sunday, will appear correctly tomorrow as 10:00 am Sunday.) But I doubt it.

This random site I found does seem to pass the correct value: https://chicagoheights.patch.com/events?when=2012-03-16. These events have additional parameters in the urls, but I’m not sure what they control.

did the demo ical work for you?

Did not see the demo before but I just tried it now. Exact same problem, for both google and ical:

Daylight savings time ends Nov 4 2012.

Event on Oct 27 2012 (before DST ends) from 6-8pm goes in accurately.

Event on Nov 17 2012 (after DST ends) from 6-8pm goes in 5-7pm.

I did come across something that said the location parameter in the url is important in calculating the time. I don’t know if that’s true or not but I do see that EM is using the EM location title, rather than the location’s physical address.

Come to think of it, I just noticed that the events don’t have an address and mapable location when they import. That is definitely needed in the url parameters, for location if not time.

Hi every one.Please help me as I am new on WordPress I just wanted to have a link of download to download the event calender , so any one can get it in his/her outlook or google calender.I using a event-manager plugin.Any help would be greatly appreciated.Thanks

@abdulmannan

can you post it separately?

Thanks for quick response agelonwl.
I have finally solved my issue as now in my event calendar I managed to show the Google calendar button under every event.Thanks a lot anyway.

Yeah, so anyway… along with the location title, the location address must appear in the url parameters. Otherwise the event doesn’t have an address when it gets to google or ical. And therefore it doesn’t have a map. And rumor has it that adding location might solve the DST problem.

These are the neil young events compared to my google calendar, set to spanish time:
Event on Oct 27 2012 – local time: 6pm – google: 8pm (wrong, I think)
Event on Nov 17 2012 – local time: 6pm – google: 7pm (correct)

Different things for both of us. I think it might also take into account DST change dates, e.g. one country changes earlier than others, meaning a bigger gap on some days.

Will have to investigate further.

Marcus, if you want another example to compare I am happy to supply any information you need.

Event in WP: https://www.ians-studio.co.uk/events/band-night/
Google calendar: https://www.google.com/calendar/b/0/embed?src=o1g3u7ouupmjjmfuirm63j18e5fbi0ag@import.calendar.google.com&ctz=Europe/London

Happy to supply any settings you need – just tell me what you need.

Ian.

@ianbutty — This looks like the same problem I was having with my recent events; events occuring post-DST but entered pre-DST were going in an hour late. With my test above, it was the opposite, as would be expected; events occuring while DST is in effect, but entered while it was not, go in an hour early. Events both occurring and entered within the same DST cycle are fine. @marcus — I think your results are the same as mine; I think the time for the second event is wrong.

I think this behavior is NOT an EM bug. However I take it at face value, until testing proves otherwise, that google (as I read somewhere — wish I could remember where) compensates for this natural problem by using event location (GEO/ADDRESS) as a work-around. Can we give google a fighting chance by passing the address?

since I can now reproduce this my side, fixing it shouldn’t be a problem. the only issue is time, this one will be a time-consumer due to repeated testing loading calendars etc. on google. Just thinking about it hurts my head ??

I agree with raskull that it might not be an EM bug, as we don’t take DST into account, yet it corrects itself at one point automatically. Again, some time will be needed to test this.

I may punt this fix for the next update (not to panic! updates are usually a week or so apart) because aside from a load of bugfixes and kinks ironed out, a lot of new features are getting done now that take far less time to sort out.

That is great news Marcus! As I’ve said before if you need me to supply and data that will help I’m more than happy to do so.

I’m sure your processes will take care of this, but I have to ask anyhow – I assume the same fix will get applied to the paid-for version, as I am considering upgrading to that version in the future.

Thanks again,
Ian.

i should make it clearer but pro is an add-on, meaning the plugin you use is never removed, pro just adds features on top of EM (proving it’s a flexible plugin!). let’s keep this on topic though as a few ppl are following this now (feel free to ask on another topic!).

usually, one instance of the error is enough, but if I need more test data will ask here, thanks!
