This field allows RTC calibration – slowing or speeding the
clock up to 10 sec/day.
For complete information about NTP including a list of recommended NTP
servers, see
The NTP Public Services Project
. To make sure you get the correct
time from an NTP server you should select the correct Time Zone for the
location of your VGA2Ethernet device.
If the VGA2Ethernet device cannot connect to the Internet and if there is an
RDATE server on the network, you can set time synchronization to use
RDATE (defined by
RFC 868
). Contact your network administrator for the
address of the RDATE server and enter the RDATE server IP address into the
Server IP Address field.
In both cases, you can control how often the date and time are updated. The
Time Update interval can be every 1, 6, 12, or 24 hours.
