| .Sh NAME | ||
| .Nm tzreload | ||
| .Nd notify timezone update | ||
| .Sh SYNOPSIS | ||
| .Nm Op Fl a | ||
| .Sh DESCRIPTION | ||
| The | ||
| .Nm | ||
| command triggers processes to reread timezone information. | ||
| The timezone information is cached in each process. | ||
| In response to a | ||
| .Nm | ||
| command, this cache is updated on the next call to | ||
| .Xr ctime 3C | ||
| and | ||
| .Xr mktime 3C | ||
| by each process. | ||
| By default, | ||
| .Nm | ||
| only triggers this update for the current zone. | ||
| .Pp | ||
| In addition to updating processes, the | ||
| .Nm | ||
| command also notifies | ||
| .Xr cron 1M | ||
| to reinitialize the job scheduler with the new timezone information. | ||
| .Sh OPTIONS | ||
| The following options are supported: | ||
| .Bl -tag -width Ds | ||
| .It Fl a | ||
| Update processes in all zones. | ||
| .El | ||
| .Sh FILES | ||
| .Bl -tag -width Ds | ||
| .It Pa /usr/share/lib/zoneinfo | ||
| Standard zone information directory. | ||
| .El | ||

| .Xr mktime 3C , | ||
| .Xr attributes 5 | ||
| .Sh NOTES | ||
| Although | ||
| .Nm | ||
| reinitializes | ||
| .Xr cron 1M , | ||
| applications that are affected by timezone changes still need to be restarted or | ||
| reinitialized if they do not reread the new timezone information before timezone | ||
| changes take place. |
