Table 22-1 Time and Date Setting Fields
FIELD DESCRIPTION
Enter the time service protocol that your time server sends when you turn on the VES. Not
all time servers support all protocols, so you may have to check with your ISP/network
administrator or use trial and error to find a protocol that works. The main differences
between them are the format.
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC-868) format displays a 4-byte integer giving the total number of seconds since
1970/1/1 at 0:0:0.
NTP (RFC-1305) is similar to Time (RFC-868) .
Use Time Server

None is the default value. Enter the time manually. Each time you turn on the VES, the
time and date will be reset to 2000-1-1 0:0:0.
