NOTE: Dell Technologies recommends configuring a standard time zone supported in Linux. Use the ? character for
command completion to view a list of supported standard time zones.
Configuration notes
If you configure a time zone for which DST is applicable and you want to downgrade OS10 to an earlier release that does not
support DST changes, do one of the following:
● Before you downgrade, disable the DST configuration or update the setting using the clock timezone command to
specify only the local time zone.
●
After the downgrade is complete, ignore the CLI error and reconfigure the setting using the clock timezone command to
specify only the local time zone.
Configure system time and date
● Enter the time and date in EXEC mode.
