Command line tool to get and set date and time on the Heliotherm heat pump.
To change date and/or time on the heat pump the date and time has to be passed
in ISO 8601 format (YYYY-MM-DDTHH:MM:SS) to the program. It is also possible to
pass an empty string, therefore the current date and time of the host will be
used. If nothing is passed to the program the current date and time on the heat
pump will be returned.
Example:
$ python3 htdatetime.py --device /dev/ttyUSB1 --baudrate 9600
Tuesday, 2017-11-21T21:48:04
$ python3 htdatetime.py -d /dev/ttyUSB1 -b 9600 "2008-09-03T20:56:35"
