When Aranet PRO base station internal clock is synchronized with NTP servers, then internally global Unix Epoch time is used. But when the user accesses the PRO base station via the graphical user interface, then this time is transformed according to the time zone configured on the user's device (phone, laptop, tablet etc.) For example, if one user has time zone UTC+5:00 on the user device and sees time 18:00 in Aranet PRO base station graphical user interface, then another user with time zone UTC+3:00 will see 16:00 on the Aranet device.
