Time Offset (sec) Number of seconds added to or subtracted
from the derived time. If you enter values
between -24 and +24,
X4000 interprets the
input as the number of hours and converts it to
the corresponding number of seconds
automatically after you press SAVE. Note: If
you select
ISDN as Time Protocol, you must
set the Time Offset to 0.
If you change Time Offset (sec) (turn back the
time), there should be no data flow.
Time Update Interval
(sec) Time interval in seconds, after which the
system time is checked and updated if
necessary. If you enter values between 1 and
24,
X4000 interprets the input as the number of
hours and converts it to the corresponding
number of seconds automatically after you
press SAVE.
For Time Protocol =
TIME/UDP, TIME/TCP or
SNTP: Current time is checked after every
Time Update Interval in seconds.
For Time Protocol =
ISDN: Current time is
checked for each first ISDN connection after
expiry of the Time Update Interval.
