When you say LED panel display, I assume you mean one of these LED matrix display units that can display a word or scroll text accross by lighting the correct leds in the matrix.  The only units I have seen configured are such that you actually communicate with them via RS232 or 485 and send a text string to the unit.  To send the date time, you would need to compile a string by converting the integer values in the status file to strings and concatenating them together to the string you want.  To go any further, I would have to have the make and model of the LED unit. 

First, dont worry about being a pain (abreviated).  Just glad I can help here and there.  Obviously sometimes I will be able to help more than others.  The problem here is that there are many different types of LED displays so it's hard to give a solid answer.  It sounds like the one you worked with took an analog signal to display a value.  I have worked with those also and usually you have a calibration on it to set the min/max value the display will show corresponding to the min/max analog input.

Concatenate is a term for "adding" strings.  You can actually add two strings together, but you can arrange them one after the other in a single addressable location.  So for a time, you would have three numbers in three different status words: hours (S:40), min (S:41), seconds (S:42).  Each would need to be converted to a string - check out the AIC instruction.  You would then have 3 strings that would need to be displayed in a way that people would understand as time.  That's where the string concatenate comes in - check out ACN instruction.  With the ACN, you have to work two strings at a time so you would need several concatenates to create the final string.  Why dont you go ahead and take that info and see what you can come up with in a program?  We can go further after you have a chance to play with these new ideas.
