Default behavior regarding NTP time server access

By default, XBee Industrial Gateway accesses an NTP time server to establish its date and time. Access to an NTP server is required, and there is a default server.

The first time an XBee Industrial Gateway powers on and goes through its startup sequence, it needs to access the NTP time server to set its time, and then attempt to connect to Remote Manager. This first-time connection step could take up to five minutes or longer on cellular networks.

For XBee Industrial Gateway Ethernet models, you can specify up to four NTP servers to be used as upstream servers in synchronizing time. The default settings for the four NTP server settings are as follows:

NTP server 1: 0.time.devicecloud.com

NTP server 2: 0.time.devicecloud.com

NTP server 3: 0.idigi.pool.ntp.org

NTP server 4: 1.idigi.pool.ntp.org

XBee Industrial Gateway cellular models use the top NTP Server entry (NTP Server 1), and leave the others blank. XBee Industrial Gateway checks all NTP servers that are configured for time-drift. Having four NTP time servers configured for an XBee Industrial Gateway cellular device would result in excessive and unnecessary cellular usage.
