0x00 = 000
0x01 = 001
...

Example:
IP address: 192.168.150.5
192 = 0xC0 (high byte)
168 = 0xA8
150 = 0x96
005 = 0x05 (low byte)
The duration of the synchronisation process depends on the settings of the NTP server. This
means that the synchronised system time is not immediately available after activation of the
NTP client.
► Do not query the synchronised system time immediately after activation of the NTP client.
