System Administration Commands tzreload(1M) NAME tzreload - notify timezone update SYNOPSIS /usr/sbin/tzreload DESCRIPTION The tzreload command notifies active (running) processes to reread timezone information. The timezone information is cached in each process, absent a tzreload command, is never reread until a process is restarted. In response to a tzreload command, active processes reread the current timezone information at the next call to ctime(3C) and mktime(3C). The tzreload notification is sent to processes within the current zone. tzreload causes processes which are using the system timezone (in /etc/default/init) to reread the contents of that file. In addition to notifying active processes, the tzreload command also notifies cron(1M), to reinitialize the job scheduler with the new time- zone information. FILES /usr/share/lib/zoneinfo Standard zone information directory.

The timezone update service is managed by the service management facil- ity, smf(5), under the service identifier: svc:/system/timezone:default Administrative actions on this service, such as enabling, disabling, or requesting refresh, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command. Refreshing this service causes the tzreload command to be run, notify- ing running processes to reload their timezone caches. Disabling this service is not recommended. SunOS 5.11 3 May 2011 tzreload(1M)
