Thanks, Michael, that's most helpful, I can call it once an hour which 
will be more than enough.

However, it seems that in the version I have for the Raspberry Pi (Laz: 
1.0.6 FPC: 2.6.0) the "Unix" unit does not contain this procedure.  I 
did find the source code for it, but I don't want to have to ask folk 
who might want to compile the clock program to have to also copy many 
lines of code from the Unix unit.  (Oh, and I tried both "unix" and 
"Unix" - both seemed to work.)

Am I missing something?

Thanks
