Configuring SNTP
There are two levels of Network Time Protocol (NTP) time servers available on
the Internet.
First-level time servers are primarily intended to act as source time servers for
second-level time servers. First-level time servers may also be capable of
providing mission-critical time services. Some first-level time servers may have
a restricted access policy.
Second-level time servers are intended for general SNTP time service needs
and usually enable public access. It is recommended that you use second-level
time servers for normal SNTP time server configuration because they are
normally located on a closer network that can produce faster updates.
It is recommended that you research any time server selection to ensure that it
can meet your specific time server requirements. More information and a list of
SNTP time servers can be found at http://support.microsoft.com/kb/262680/.
If the time on the time server is more than the threshold value away from the
current time on the QuickPanel View, then the time is not updated. Setting the
Threshold to 0 tells the utility to always accept the time from the server. This
setting would be useful in a case where the backup battery has died and the
QuickPanel View was power cycled, since the internal clock would have reset
back to January 1, 1980 12:00 am.
