Need to know the time - accurately for your next project?
The code below allows your PIC to log into a network timeserver and it (eventually) writes the time to a Dallas RTC (code not supplied).
The PIC checks the NET TIME every power-up and thereafter every 4 hours. If it doesn't make connection, it tries an alternate time server. If THAT doesn't work (after retries) it gives up and tries again 4 hours later. A Lantronix XPort handles the connection to the net.

Re: PIC temperature, when is it too hot
How do you figure the power dissipation is 600mW?
HenrikOlsson Today, 22:17It would be if all the of the 120mA would go out the Vss pin, thus 5VÄ*120mA. But now, most of the current is going out the I/O-pins with FAR less...
