Description Philippe ROUBACH 2014-08-24 09:43:13 UTC
opensuse 13.1 x86_64
kde 4.13.3
akonadi 4.13.3

1. first experiment
1.1 in google agenda

i create a rendez-vous at 15 h

1.2 in korganizer

some time later

the rendez-vous is added at 15 h

2. second experiment
2.1 i buy a ticket to the french railway operator SNCF via their android app

this automatically creates a rendez-vous à 7 h 10 in android agenda

2.2 in google agenda

some time later a rendez-vous is created at 7 h 10

2.3 in korganizer

some time later a rendez-vous is created at 9 h 10 !!!!!!

3. i check this

in android gmt+2
in google gmt+1 (I did not find any parameter about energy saving time but google agenda displays well the gmt+2)
in korganizer (no parameter) i assume it uses kde settings thus gmt+2

accurately :
- in kde settings "date et heure" is set to europe/paris (PMT) (i assume gmt+1)
- in kde clock settings 
"clock by default at" is set to "local"
"define automatically date and hour" is not checked

- the hour is set by ntp service managed by opensuse tool thus gmt+2
- hardware clock uses UTC
Comment 1 Philippe ROUBACH 2014-08-24 15:33:21 UTC
1. 

i open the rendez-vous of the first experiment

the hour is 7 h 10
the zone is "europe/paris"

2. 
i open the rendez-vous of of the second experiment
the hour is 7 h 10
the zone is "UTC"

what software does the error to set to "utc" the zone ?
Comment 2 Philippe ROUBACH 2014-09-22 08:39:47 UTC
ok now i have a better definition of the pb .

the event sent by SNCF uses utc (gmt+0) time
for example if you get a train à 13 h 18 then the hour of the event sent by SNCF is  11 h 18 utc
then
android using utc+2 creates an event at 13 h 18 : this is good
google using utc+2   cretates an event at 13 h 18 : this is good
but
korganizer(akonadi) creates an event at 15 h 18    : this is wrong

it seems it uses the kde clock time instead of utc time and does not care about the parameters "utc" in the event sent by SNCF

kde clock time is "europe/paris" and "europe/paris" is utc+2
thus
utc+2+2 leads to 15 h 18

notes : SNCF is the french railways company
Comment 3 Philippe ROUBACH 2014-09-22 09:06:58 UTC
opensuse 13.1 x86_64 
kde 4.14.1 akonadi 4.14.1

i made this experiment :

with android i create an event at 10 h by setting the time at "8 h utc"
then
android using utc + 2 creates an event at 10 h : good
google using utc+2 creates an event at 10 h : good

korganizer creates an event at 12 h : bad

now i am sure that korganizer does not take care of the time zone of the event sent by another tool
Comment 4 Philippe ROUBACH 2014-12-15 15:06:53 UTC
opensuse 13.1 x86_64 
kde 4.14.3

pb still there

any chance to get a fix ? thanks .
Comment 5 Philippe ROUBACH 2014-12-20 06:55:35 UTC
i see that you assigned this report to Daniel Vratil.

i think D Vratil is a developper of akonadi but not korganizer .

i think this is a bug about korganizer and the pb is in korganizer not in google akonadi backend thus it must be assigned to another person , perhaps laurent montel . no ?

or at least add laurent montel.
Comment 6 Philippe ROUBACH 2015-01-01 06:40:19 UTC
another experiment 
i buy a train ticket at  "Capitaine Train" via their android app 
in kmail i receive a mail with a event .ics
i add the event to korganizer by clicking "accept" the event
in korganizer an event is created at 12 h 11 !

this time the shift is 1 h instead of 2 h because we use winter time .
Comment 7 Allen Winter 2015-03-08 01:03:37 UTC
I really need to see the calendar event.  any chance you can send me such an event?  you can sanitize it, except for any info related to dates or timezones.
Comment 8 Philippe ROUBACH 2015-03-08 07:52:14 UTC
here is a ticket to take train from Pessac to Arcachon at 14 h 11 mn (2015/02/27)

korganizer creates an event for 15 h 11 mn
