Configuring The Channel Settings - 3Com VCX V7122 User Manual

should use is a configurable parameter that can be specified either in the ini file
(NTPServerUTCOffset) or via an SNMP MIB object.
If required, the clock update is performed by the client as the final step of the update
process. The update is done in such a way as to be transparent to the end users. For
instance, the response of the server may indicate that the clock is running too fast on the
client. The client slowly robs bits from the clock counter in order to update the clock to the
correct time. If the clock is running too slow, then in an effort to catch the clock up, bits are
added to the counter, causing the clock to update quicker and catch up to the correct time.
The advantage of this method is that it does not introduce any disparity in the system time,
that is noticeable to an end user, or that could corrupt call timeouts and timestamps.
