Default behavior regarding NTP time server access
By default, XBee 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 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
For XBee Gateway Ethernet
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 Gateway cellular models use the top NTP Server entry (NTP Server 1), and leave the others blank. XBee Gateway checks all NTP servers that are configured for time-drift. Having four NTP time servers configured for an XBee Gateway cellular device would result in excessive and unnecessary cellular usage.
