For fun, visit the XLoadtime homepage, at:

http://staff.washington.edu/xyzzy/xloadtime/

To compile, just type make.  The program uses for the most part the same
options and resources as xload.  Two extra options are for the extra features.

First is -12hour or the boolean resource 12Hour, this changes the clock from a
24hour clock to a 12 hour clock with AM/PM.  Nice for us Americans.

Second, is -cpu or the boolean resource Cpu.  This displays vertical bar(s) on
the right side of the window.  Each bar represents the average CPU usage
during the update interval.  With kernel 2.2.0+, machines with more than one
CPU will have more than one bar.  Multiple CPU bars will not work on 2.0.x
kernels, you will just get one bar. 

This is the command line I use:

xloadtime -update 5 -12hour -cpu -fg Black -bg gray52

Alternatively, one could put resources like this in their .Xdefaults file,
instead of the command line options.  Or use a combination of the two.

XLoad*background:	Black
XLoad*foreground:	gray52
XLoad*12Hour:		True
XLoad*Cpu:		True
XLoad*Update:		5
XLoad*Font:		-misc-fixed-bold-r-normal--*-120-*-*-c-*-iso8859-1
