Configuring the System Time Using the Network Time Protocol 69
Configuring the
System Time Using
the Network Time
Protocol
To configure the system time of the Webcache using the Network Time
Protocol, you must enter the following information in the Getting Started
wizard or Time Configuration command in the Web interface:
1 Select a timezone from the options in the Timezone drop-down list.
The Webcache automatically performs daylight savings adjustments
according to the timezone that you have selected.
2 Choose Network Time Protocol by clicking the appropriate radio button.
3 Enter the IP address of the NTP server that you want to use in the NTP
Server IP Address field.

Manually
To manually configure the system time of the Webcache, you must enter
the following information in the Getting Started wizard or Time
Configuration command in the Web interface:
1 Select a timezone from the options in the Timezone drop-down list.
The Webcache automatically performs daylight savings adjustments
according to the timezone that you have selected.
2 Choose Manual Time Configuration by clicking the appropriate radio
button.
3 Enter the current day, month, year and the current time (in 24 hour clock
format) in the appropriate fields.
4 Click Apply Now as soon as you have manually entered this information

done this.
System Time and
Performance
Graphs
When the system time of the Webcache is set manually, all of the current
Performance Graphs are reset and all previous graph history is lost. You
should therefore only change the system time when it is absolutely
necessary. The following system time changes affect the Performance
Graphs in this way:
■
The system time is manually configured.
■
The system time is changed from Network Time Protocol to Manual
Time Configuration, or vice versa.
■
The IP address of the Network Time Protocol server is changed.
