| Summary | 0006133: Timezone updates not being taken into account | ||||
| Description | The executive summary:
If you inspect the ics for the meeting that was shared by Thunderbird, you can see it included the entire historical timezone changes for Sao Paulo since 1914. Is it possible SOGo is unable to parse the entire thing and ends up not knowing Brazil stopped doing DST in 2019? These are the last entries in the Sao Paulo section: | ||||
| Tags | No tags attached. | ||||
 |
Note that we have the same problem with a Chilean user, so this isn't specific to Sao Paulo. |
 |
Hello, could you give me the full ics file? SOGo use the iana databases for its timezone -> https://www.iana.org/time-zones |

Hi Quentin! I've got the ics from that motivated the report and anonymized it. Hope it is useful! calendar.ics (11,373 bytes)
