Thanks for that idea.  I had already figured out the recoding necessary
using options to the date command to reformat the value in an update of the
script I had posted to the list a month or two ago, but I like yours
better.  My problem isn't so much getting the time into the right format,
but that the system no longer will wake from suspend-to-disk (and power down
to standby power only, essentially "off").  I'm sure the kernel developers
would say I have a defective mobo, but I suspect they didn't do a very large
sample of mobos.  Whatever they did to "improve" the alarm code broke it on
my system.  That makes me %^(.
