New package for controlling termination of the model based on the wall clock:
This is handy for those of us who keep losing 5000 cpuhours because the model
took 5 minutes longer than it did the day before.

To use:
 In package.conf, add   runclock
 In data.pkg, add       useRunClock=.TRUE.
 Add data.runclock to read
    &RUNCLOCK
    RC_maxtime_hr=2,
    RC_maxtime_mi=30,
    RC_maxtime_sc=0,
    &

The package also write the delta Wall Clock between each model step.
Who can explain a 30% slow down after 60 iterations? Who even knew about it?
Now you can find out lots of dark secrets about the EM EYE TEE GEE SEE EM...
