Original GitHub issue: https://github.com/netblue30/firejail/issues/5448

Description

E-mail clients show wrong time of received mails and vcalendar. (experienced with claws-mail), due to using timezone UTC instead of system configured timezone.

Steps to Reproduce

 > date +%Z
 CET

 > firejail --quiet --profile=email-common date +%Z
 UTC

possible fix

adding localtime to line private-etc in file email-common.profile

new line in file email-common.profile should look like:

private-etc alternatives,ca-certificates,crypto-policies,dconf,fonts,gcrypt,gnupg,groups,gtk-2.0,gtk-3.0,hostname,hosts,hosts.conf,ld.so.cache,ld.so.preload,machine-id,mailname,nsswitch.conf,passwd,pki,resolv.conf,selinux,ssl,xdg,localtime

edit

above fix solves displayed time of received e-mails, but not vcalendar entries. claws-mail vcalendar plugin seems to use libical to calculate time.

Nice find. The private-etc fix for the displayed time of received e-mails can be added right now. Can you ceate a PR for that part of the issue? If so, please keep in mind that the option is alphabetically ordered, so tacking on localtime at the end of the string is not the way we do things...

I'm not sure there's anything firejail can do about the vcalendar plugin behavior, but we'll see about that later.
