tzreload(1M) System Administration Commands tzreload(1M)NAMEtzreload - notify timezone update
SYNOPSIS
/usr/sbin/tzreload [-a]
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). By default, the tzreload notification is sent to the pro‐
cesses within the current zone.
In addition to notifying active processes, the tzreload command also
notifies cron(1M), to reinitialize the job scheduler with the new time‐
zone information.
OPTIONS
The following options are supported:
-a
Notify processes in all zones.
FILES
/usr/share/lib/zoneinfo
Standard zone information directory.

NOTES
Although tzreload reinitializes cron(1M), applications that are
affected by timezone changes still need to be restarted or reinitial‐
ized if they do not reread the new timezone information before timezone
changes take place.
