Nextcloud Calendar


A strange thing with Nextcloud calendar happens to me.
I explain:

On my phone, I use a calendar application.
On my server I use a ksh script who puts events on another database. The ksh script use unixtime which is in the table oc_calendarobjects and transforms it into human date (YYYY-MM-DD).
When I bring in a new event with the calendar phone application, and having to synchronize, I execute the ksh script and I see that the unixtime transformed into human date has 2 hours in gap (13h instead of 11h).

When I try with another calendar phone application, it’s OK, no gap.

BUT… The event which I added with the first application appears without gap in the second application.

I cannot determine if it is a problem with the application or with nextcloud calendar.

If someone have an idea…
