The date and time section allows the setting of the ADC’s date/time characteristics, including the timezone in which the ADC is located. Together with the timezone, the date and time play a vital part in the cryptographic processes associated with SSL encryption.
Manual Date and Time
Time Zone
The value you set in this field represents the timezone in which the ADC is located.
· Click on the drop-down box for the Time Zone and start typing your location.
For example London
· As you begin typing, the ADC will automatically display locations containing the letter L.
· Continue typing ‘Lon,’ and so on – the locations listed will be narrowed down to ones containing ‘Lon.’
· If you are in, say, London, then choose Europe/London to set your location
If the Date and Time is still incorrect after the above change, please change the date manually
Set Date and Time
This setting represents the actual date and time.
· Choose the correct date from the first drop-down or,
alternatively, you can type the date in the following format DD/MM/YYYY
· Add in the time in the following format hh: mm: ss, for example, 06:00:10 for 6 am and 10 seconds.
· Once you have entered it correctly, please click Update to apply.
· You should then see the new Date and Time in bold characters.
Synchronize Date and Time (UTC)
You can use NTP servers to synchronize your date and time accurately. The NTP servers are located globally, and you may also have your own internal NTP server when your infrastructure has limitations on external access.
Time Server URL
Enter a valid IP address or fully qualified domain name (FQDN) for the NTP server. If the server is a globally located server on the Internet, we recommend using an FQDN.
Update at [hh:mm]
Select the scheduled time at which you would like the ADC to synchronize with the NTP server.
Update Period [hours]:
Select how often you would like synchronization to occur.
NTP Type:
· Public SNTP V4 – This is the current and preferred method when synchronizing with an NTP server. RFC 5905
· NTP v1 Over TCP – Legacy NTP version over TCP. RFC 1059
· NTP v1 Over UDP – Legacy NTP version over UDP. RFC 1059
Note: Please note that synchronization is in UTC only. If you wish to set a local time, this can only be done manually. This limitation will be changed in later versions to enable the ability to select a time zone.
