Use Time Server
When Bootup
Select the time service protocol that the timeserver uses. Not all time servers
support all protocols, so you may have to use trial and error to find a protocol
that works. The main differences between them are the time format.
When you select the
Daytime (RFC 867) format, the switch displays the day,
month, year and time with no time zone adjustment. When you use this format it
is recommended that you use a Daytime timeserver within your geographical
time zone.
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).
None is the default value. Enter the time manually. Each time you turn on the
device, the time and date will be reset to 2000-1-1 0:0.
