Thunderbird Timezone error

JG

For the past couple of months, I've been receiving a timezone error pop up in Thunderbird that seems to point at todoist. Here's an example of the error from the Thunderbird error console with some info redacted (XXXXX):

[JavaScript Error: "Unknown timezone "GMT -08:00" in "XXXXXX". Treated as 'floating' local timezone instead: November 11, 2013 10:00 AM

This seems to be affecting recurring appointments only. Editing the tasks with a new recurring time did not resolve the problem.

Hi,

Do you have our iCal Feed added to the calendar options within Thunderbird, or are you just using our extension?

Which version of Thunderbird are you running? If you are using the iCal feed, please try removing it, and re-adding it.

Thanks,
Brendon.

Yes! I did have an iCal feed that I had forgotten about. Though it wasn't active, it was apparently causing the error. Removing it resolved the issue. Thank you!

For future reference, yes also using the Todoist extension for Thunderbird. Thunderbird version 24.1.0

Hi,
I'm having the same issue on two machines. I run Kubuntu 14.04 with Thunderbird -- Lightning. The error started appearing a few weeks ago (while still in Kubuntu 13.10).
Removing and re-adding the calendar didn't change anything.
The error doesn't seem to be critical but pops up after every refresh.

Cheers,
Roey

Griffen,

If you can respond and let me know if you were also using a version of Linux that could be of some use in resolving this issue.

Regards,
Brendon.

Interesting...
Thanks for the help though.
Let me know if there's anything I can do to help you get to the bottom of this.

My exact pop-up error reads:
"See Error Console: Unknown timezones are treated as the 'floating' local timezone."

Haven't looked into the error console though.

Cheers,
Roey

Roey,

Now I didn't ask, as from my understanding it should not cause this issue with iCal, but. Please try to make sure Todoist.com's settings, your desktops settings and any other places you use Todoist are on the same Timezone.

Regards,
Brendon.

Confirmed. Everything (computer, thunderbird, and Todoist.com) are all set to GMT +0200 Europe/Vienna.
Still getting the error (and just make clear, removing ToDoist calendar from thunderbird makes the error stop appearing).

Same here. I'm experiencing same problems as Roey Angel on Thunderbird
24.5.0 running on Windows 8.1

Hi,

I will pass this along but we are not sure what is causing this. Also, removing the feed should resolve it but it would appear that is not the case for everyone.

Regards,
Brendon.

Anyone knows any working calendar solution?

Beyond having error messages overflowing my thunderbird's error console my bigger concern is that as of this moment after 2 days I still haven't found a single working solution to visually view my events in a Google Calendar-like interface where I could drag n drop move around the events as needed.

Starting from scratch I download-install-config Thunderbird 31.3.0 with the same google account I'm using Todoist with

I did add the Todoist thunderbird addon, but that just gives me the online like interface in a sidepane

I'm looking for a bidirectional ical support instead

As Thunderbird doestn't have a built-in calendar interface I installed: Lightning 3.3.2 into it

On the left pane of lightning I went on creating a new calendar, adding it from network and added the URL present in the online settings of TODOist

Now upon clicking on Synchronize comes a Tsunami of error messages all with the same format like this:

"[JavaScript Error: "Unknown timezone "GMT +00:00" in "Reply to FedEx". Treated as 'floating' local timezone instead: 06 January 2015 10:00
BEGIN:VCALENDAR
PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN
VERSION:2.0
BEGIN:VEVENT
UID:**************@todoist.com
SUMMARY:Reply to FedEx

DESCRIPTION:Project: !!! Urgent / Fontos !!!\n\nComplete this item: \nhttp

END:VEVENT
END:VCALENDAR
"]"

it seems like all of the events are posting their timezone with a different string that Lightning would expect

May be it's just a space in the string, or some other format error

In the Lightning calendar settings there's a timezone option which is set to Europe/London GMT+ 00 aswell, same as in TODOist

Please advise what other information/assist/help is needed to get to the bottom of this issue

As a side note/separate issue: if I add the same iCal feed URL to google calendar web interface, I do see it initially populated, but no further updates appear that I commit from TODOist even if I reload the calendars/site

I forgot to add: removing,readding the calendar in Lightning have no effect on the error messages

Remove the TODOist calendar from Lightning does make the errors go away but then I donn't have them available at all

so it's like cutting your leg when it only has muscle cramp....

"I'm looking for a bidirectional ical support instead".

As far as I know, ToDoIst ical is read-only (i.e. one-way). Try searching, I am sure somebody from staff mentioned that. (Unless they have changed it).

Hi Nanoprog,

Yes, we don't have bidirectional ical support. As for the Google Calendar integration, Google only refreshes iCal feed once a day but we're looking into improving this.

Regarding the Lightning Calendar problem, we may need to report it as bug to them. I'm using the iCal feed using the default Apple Calendar app and I'm not getting any timezone related errors.

Clyde

Hello and thank you for the quick reply

Unfortunately after loads of digging I came to similar conclusion

As I don't have any Apple only Dozer and Android products/devices seems I'm stuck with the online solutions

Right now I gave a shot to Sunbird and though it's far from ideal (even with desktop agent the website is hard to handle from droid browsers) at least it gives some control/check back on the windows desktop of mine

but that takes away the portable aspect, as I can't often afford "desk-time"

hope in future it changes

best wishes
Greg

As far as I know, this error message doesn't break Thunderbird functionality. While it is annoying, it doesn't appear to affect Thunderbird.

unfortunately it does: say you are to move any event up and down in time, it will fail to pass the updated event details to TODOist on sync and thus renders it completely useless

though it's faster than 24 hrs as refreshment it becomes view only aswell thishow

apart from that in the background javascript keeps trying in the background which results in not much but around 10-20% of cputime of my core2 2.53ghz

while that's not a large number being a constant strain does add up with others-->slows the machine down

thishow I need to shut/open thunderbird/lightning on a per demand basis

"unfortunately it does: say you are to move any event up and down in time, it will fail to pass the updated event details to TODOist on sync and thus renders it completely useless"

If I understand correctly, you want to update event in Thunderbird and sync changes to ToDoIst. But as Clyde mentioned, this is not supported. You can only view ical feed, you *cannot* modify it.

Actually though I wanted it to update I didn't realize that it wasn't failing because of the timezone issue but because of the iCal relation to the whole calendar at the first place

my mistake - the whole thread of mine thishow is of nonsense
sorry
