With the "T"<unix-time-stamp> option in the help menu you can set the system time on the board. There are some extra functions when a RTC shield of type DS1307 is connected to the board. When restarting the board, the time from the connected RTC is set. The "T"<unix-time-stamp> help function is not only changing the system time but also the time of the RTC when connected to the I2C bus. In this way it is possible to set or correct the time to both the board and the RTC. The unix time stamp can be easily found on the internet; e.g. convert the correct time to UNIX formatand use the T command from the help menu.
Remark: When connected to HMI, the HMI will update the time. When a RTC is connected, the time of the RTC is also updated.
Example for setting the time in the serial monitor: T1444511436
