Users or sysadmins must restart their apps or programmers to understand new settings when they set the TZ variable. Timezone information is most commonly stored in a timezone database known as zoneinfo This allows users in multiple time zones to use the same computer, with their respective local times displayed correctly to each user. Standard library routines are used to calculate the local time based on the current timezone, generally supplied to processes through the TZ environment variable. Rather than having a single timezone set for the whole computer, timezone offsets can vary for different processes. Most Unix-based systems, including Linux and macOS/OS X, keep system time as UTC. First, use the following instructions to set the time zone per user. You can set the time zone system-wide using this method. Most adjacent time zones are one hour apart and, by convention, compute their local time as an offset from Greenwich Mean Time. How do I configure Fedora Linux or any Unix-like operating system to set the time zone on a per-user basis using bash shell?Ī time zone is a region of the Earth that has adopted the same standard time, usually called the local time. We are developing Linux-based applications, and we would like to set the time zone on a per-user basis for the individual user.
