+
+USE CASE
+When running Venus OS on a Raspberry Pi there is no real time clock.
+As my application is on a boat there may be no internet connection.
+In this case the local device time is not set at startup so logs are created with the wrong time stamps.
+
+SOLUTION
+
+This is a shell script that runs at startup and reads the time from the data stream from a USB GPS device. If time information is found in the data stream it is read and used to set the device local time. As a result Venus OS logs are stamped with the correct time.
+
+If the USB GPS device is not connected or not producing a data stream with the right data
+the script will exit. The script is run in the background to ensure that it does not block other
+parts of the Venus OS initialisation.
+
+REQUIREMENTS / TEST ENVIRONMENT
+This has been tested in the following environment.
+It should work in other cases.
+
+   Venus OS 2.6
+   RPI 3B+
+   USB GPS device with NMEA data stream output.
+
+INSTALLATION
+
+Place the gps-time.sh file in directory /data/venus-rpi-setup/
+Make sure it has execute set
+>chmod a+x /data/venus-rpi-setup/gps-time.sh
+
+Place a copy of rc.local in directory /data
+[ Or add the lines from from rc.local to you own rc.local if you need to
+  run other things as well ]
+Make sure rc.local has execute access
+>chmod a+x /data/rc.local
+
+If you choose to out gps-time.sh somewhere else, 
+then change rc.local to refer to the right place.
+
+IN USE
+You can check the results of the script running in the log file.
+/var/volatile/log/gps-time
+
+If all goes well the time on the Venus OS console will be correct at start up.
+
+Hope it works for you
