Annual event is shown twice

Hello,

Can you try the JEvents RC3.4 and try again?

Many thanks
Tony

Thanks for the fast reply.

I’ve installed and tested version 3.4.0RC5 Stable.
The symptoms are exactly the same as in version 3.2.19.

Kind regards

Can you send me super user login details and how to replicate the issue on your site?

Thanks
Tony

Dear,

Thanks for your reply.

Below you can find the access data of the test environment (JEvents v3.2.20 Stable).

If I create an event with the settings as shown below, I should only have an event every last Thursday of August. Strangely enough this event is also created on each last Thursday of January.
I’ve made an event called “Test 2 (also event in January)” with the issue.
By pressing the “repeats”-button in the event summary on the backend you have a nice overview. So as you can see the problem starts first on 2017-01-26 and keeps repeating.

Start date: 2016-08-25 Start date: 20:00
Start date: 2016-08-25 End date: 23:59
Repeat type: Monthly
Repeat Interval: 12 months
Repeat Count: 99 repeats or Repeat Until 2100-01-01 (as long as possible)
By Day: Thursday
Which Week(s)?: week 1
Count back from month end: yes

When I create an event only ±20 repeats or less, there are no events created in January.
I’ve created an event called “Test 1 (works fine)” with the settings as shown below.

Start date: 2016-08-25 Start date: 20:00
Start date: 2016-08-25 End date: 23:59
Repeat type: Monthly
Repeat Interval: 12 months
Repeat Count: 20 repeats
By Day: Thursday
Which Week(s)?: week 1
Count back from month end: yes

If you have questions, please let me know.

Kind regards,

The issue is caused by a constraint in JEvents that blocks repeats beyond the end of 2036 so the data is getting corrupted by doing this - hence the bad dates.

The reason for this is that 32bit servers are unable to handle dates outside the range 1902-2037. You could try to relax this condition in the code and see if it works on your server.

Change line c. 430 of components/com_jevents/libraries/iCalRRule.php from

if (($currentYear+$this->rinterval)>=2037) break;

to

if (($currentYear+$this->rinterval)>=2237) break;

Does that resolve the issue?

I’ve changed the code but the problem persists.

Did you then edit and resave the event?

Indeed, I’ve edit and resave the event.
I’ve also created a new event with the same settings.

You are running on a 32bit window server or have a 32bit version of PHP - this cannot handle dates in the date() and strftime() functions beyond 2038.

Unless you are locked in to a contract on this server you may be better off moving to a Linux hosting service.

Indeed, this website is placed on a windows platform with a php x86 architecture.
I’ve installed Jevents on another website on a Linux hosting and indeed it works fine there.

So I will discuss this issue with the hosting company and take the necessary steps to solve this.
Thanks a lot for the support.

Thanks for letting us know :-) Good luck with your resolve.

Many thanks
Tony
