system_time
represent a 32 bit timestamp in seconds since JAN-01-1970. The timestamp has to be
initially set by the Modbus master because the device has no back-up battery and so it would start at 0
(00:00:00 JAN-01-1970) after a reboot.
The timestamp is incremented by the device but anyway it has to be set by the master at defined intervals
to prevent time offsets.
