Time zone settings

Since MOR 11 you can set timezone from the GUI in user settings for each user.
This setting applies only to statistics pages, etc. When generating invoices, reports (pdf, csv) - actual server time is still used.

Timezone settings can be changed in /etc/sysconfig/clock:

mcedit /etc/sysconfig/clock

Timezone /etc/sysconfig/clock configuration example

ZONE="Europe/Vilnius"
UTC=true
ARC=false

An example of a correct configuration for France:

ZONE="Europe/Paris"
UTC=true
ARC=false
