Items
Description
the window is grayed out.
Time zone
Used to select a time zone from the pull-down menu.
NTP
Sets whether to enable or disable the NTP function.
Enable
Disable
With [Enable] selected, the MMB synchronizes with the time of the NTP server
specified below in [NTP1] to [NTP3].
It is synchronized with immediately after the Enable setting at the time of the server
side regardless of the setting of NTP Time Correction Mode.
The default is Disable.
NTP Time
Correction Mode Sets an NTP time correction mode.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
- [Step]:
If the time difference with the NTP server is less than 128 milliseconds, the
MMB
uses Slew mode (0.0005 seconds per second) to correct the time. The
MMB corrects the time as soon as the difference reaches 128 milliseconds.
If the time difference is outside a range of -
1000 to +1000 seconds (16
minutes and
40 seconds), the NTP function stops.
- [Slew]:
The following action is taken depending on the time difference with the NTP
server:
If the difference is within a range of -
600 to +600 seconds (10
minutes), the
NTP executes Slew adjustment, which corrects the time
at a rate of up to 0.0005 seconds per second without reversal.
If the difference is outside a range of -
600 to +600 seconds (10
minutes) and within a range of -1000 to +1000 seconds (16 minutes
and 40 seconds), the
NTP executes Step adjustment. (In this case,
the clock may be reversed.)
If the difference is outside a range of -1000 to +1000 seconds (16
minutes and 40 seconds), the NTP function stops.
The default is Step.
NTP 1
Sets the IPv4 or IPv6 IP address of the Primary NTP server.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
NTP 2
Sets the IPv4 or IPv6 IP address of the Secondary NTP server.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
NTP 3
Sets the IPv4 or IPv6 IP address of the Third NTP server.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
Current Sync Status
Displays the synchronous status with the current NTP server.
When synchronized: Displays the latest synchronous time together with the IP
address as follows:
xxx.xxx.xxx.xxx yyyy-mm-dd -dd:mm:ss
When not synchronized: Displays "No Sync."
