2.17 Clock

2.17.1 Overview

The smart phone secures the accuracy of the clock by synchronizing the time with the mobile
phone network (NITZ synchronization). However, in the case of models that do not have a phone
function, it is common to use the Internet and time synchronization (NTP synchronization) because
there is no time synchronization function with the mobile phone network. However, it is not
unusual to operate without connecting to the Internet when using terminal for business use.
We recommend that you install an NTP server in your company if your operation is as follows.
① Using a model without telephone function
② Using WiFi, but not connecting to the Internet
③ Clock accuracy is important
In case not possible to connect to the internal NTP server, set clock manually.

2.17.2 Time synchronization

Since the setting of "Synchronize time with network" is enabled in the default of IT-G400, it is not
necessary to change this setting if you use the mobile phone network or the Internet.
On the other hand, if using the above network time synchronization is not possible in any reason, it
is common to set up an NTP server inside the company, but there is no "NTP server address
setting" in Android standard function.
In case of IT-G400, NTP server address can be set by using the Kitting Tool included in this basic
development kit.
NTP server address can be set also by using MDM software (such as mobicon).
To synchronize time with the local NTP server with IT-G400, set the NTP server address using the
Kitting tool or MDM software (mobicon etc).
If you do not synchronize the time using the network, disable "Automatic date & time" and
"Automatic time zone" from [Settings] → [Date & time].
