C)lock displays time on system:  Entering a "C" will display the
current time and how long you have left.  RBBS restricts the amount
of time you can stay on the system so that other callers have a 
chance to use the system.

TIPS:  A quick reminder of time left on the system is also the 
"xx minutes left" that precedes the command prompt on RBBS-PC.
