Configuring the device as an SNTP server
2
Syntax: sntp sync
By default, Brocade switches and routers do not change the system time for daylight saving time.
To enable daylight saving time, enter the clock summer-time command.
Brocade(config)# clock summer-time
Syntax: [no] clock summer-time
Although SNTP servers typically deliver the time and date in Greenwich Mean Time (GMT), you can
configure the Brocade device to adjust the time for any one-hour offset from GMT or for one of the
following U.S. time zones:
• US Pacific (default)
• Alaska
• Aleutian
• Arizona
• Central
• East-Indiana
• Eastern
• Hawaii
• Michigan
• Mountain
• Pacific
• Samoa
The default is US Pacific.
To change the time zone to Australian East Coast time (which is normally 10 hours ahead of GMT),
enter the clock timezone gmt command.
Brocade(config)# clock timezone gmt gmt+10
Syntax: [no] clock timezone gmt | us <time-zone>
You can enter one of the following values for <time-zone>:
• US time zones (us): alaska, aleutian, arizona, central, east-indiana, eastern, hawaii, michigan,
mountain, pacific, samoa.
• GMT time zones (gmt): gmt+0:00 to gmt+12:00 in increments of 1, and gmt-0:00 to gmt-12:00
in decrements of 1 are supported.
New start and end dates for US daylight saving time
NOTE
This feature applies to US time zones only.
The system will automatically change the system clock to Daylight Saving Time (DST), in compliance
with the new federally mandated start of daylight saving time, which is extended one month
beginning in 2007. The DST will start at 2:00am on the second Sunday in March and will end at
2:00am on the first Sunday in November.
