millis() and lcd.clear() coding

I was wondering if there was a way to use the millis() statement and work it so that it will count seconds and minutes. I tried simple division and statements such as
x = millis();
if ( x == 1000)
{
x = 0;
z++;
}
I was also wondering if it was at all possible to erase one character instead of the entire screen from an LCD using the lcd.clear() statement which out clearing the screen and reprinting everything but the one character i do not want.

Thank you for your input.

Im not sure if it would work but try lcd.clear(0,0); and see if it clears the first block. Its worth a try :slight_smile:
