Request: Timezone read from Browser confuses visitors
Hi Sergey.
Thank you for your wonderfull appointments app. It´s a blast and makes life sooo much easier ;) I just sent you a symbolic obulus and I really hope it helps continuing the work you do!
Nevertheless I´d like to ask for a little feature request as I´m having a little problem with certain "safe" browsers. Modern "safe" browsers (such as "MULL" on Android and "TOR Browser") seem to prevent fingerprinting. One mechanism of preventing this is to answer a request for the timezone in an "obfuscated" manner.
Appointments seems to read the timezone from the browser. Means: Appointments shows "wrong" Appointment time or date if the visitor is using this browsers and is not aware of the timezone he´s requesting the appointment. We had the first 2 cases here with people using this.
Yes, I am showing the timezone to the visitor (as made available in the extended settings) - but I guess nobody will get it.
Could you please make it possible that we set a timezone on our own (probably the one set in nextcloud for the source calendar) and that the timezone is not relying on the output of the browser API ?
Thank you!
At the moment most of the work is going into version 2 therefore I can not do a full implementation via the settings dialog for v1. However, a workaround is possible in v1.5.14, timezone can be controlled via URL query parameter...
For example to force Tokyo timezone, you would add ?tz=Asia/Tokyo to the end of your appointments page URL:
Example: https://your.domain.com/index.php/apps/appointments/pub/SoMeToKeN/form -> https://your.domain.com/index.php/apps/appointments/pub/SoMeToKeN/form?tz=Asia/Tokyo
The list of valid time zones can be found here: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
Wow. That was fast. Thank you very much! It works like a charm now! Keep up the brillant work and thanks again for the barrier free support you provide here. If there is anything I can help you with (like betatesting 2.0 or whatever) just let me know.
Maybe simpler solution would be to use the locale set in the Nextcloud user profile? This would save having to develop it in the settings of this app, and would be better for UX since the timezone only has to be set once.
