Usage Information The standard time zone option applies the predefined offset for the selected standard time zone, including DST
changes that apply to the local time. After you configure this command, OS10 uses the updated local time in all
logs and timestamps. You can use the ? character or press the tab key for command completion and view a list
of supported standard time zones. To view a list of supported standard time zone names, see the Time zones and
UTC offset reference section. Define region names with a "/" at the end of the string. The "/" character indicates
that a time zone string follows the region name. For example, "Asia/Calcutta." The no form of the command
resets the local time to UTC.
