time and date


Can anyone help me on the arduino software clock library, it doesn't show anything when i start the program is it possible that it doesn't get the time from the PC through the serial? also i want to display it on my LCD.

If you're referring to the DateTime library, there's no automatic installation: you need to include something explicit in your code to set the clock.

I recently did an app that sends timestamped data to a webserver via Ethernet, and my solution was to have the webserver send out its time() value in every HTTP response, so the Arduino continuously resynchs itself with the server.
