Bug#538971: [systemsettings] Timezone is global and not local to user

[Bastien ROUCARIES <roucaries.bastien@gmail.com>]

Package: systemsettings
Version: 4:4.2.4-1+b1
Severity: normal

On unix timezone is local and not global. My computer run in UTC and 
conversion is done using TZ environment variable. Please use TZ environment 
variable instead of changing global time zone (moreover it does not need to be 
superuser)
