Interesting...  I thought the semantics were such that if the start time
is missed, the next day is used.  I'll have to re-read the cron
documentation.

Is your user an administrative user?  Is your home on a network share?
Try changing the above to

*/5 * * * * /bin/date >> /tmp/date.out 2>&1

Does /tmp/date.out get created?

It is possible, but the group shouldn't matter.  Note that '+' at the end
of the permission string means that there are extra ACLs set for that
directory -- some of these may deny the necessary access.

Ok, just a sanity check.

That's ok -- bash sets SHELL if it's not set in the parent environment.

Aside from the fact that you seem to have run "set" from a bash shell,
whereas your prompt above is from a "cmd" shell, and that you use
"/cygdriver" instead of the standard "/cygdrive", the output looks fine.

FWIW, I just installed "cron" from scratch using /usr/bin/cron-config, put

*/5 * * * * /bin/date >> /tmp/date.out 2>&1

in my crontab, and sure enough, /tmp/date.out got created.  Try that one
first, and if it works, you'll know that there is some issue with your
home directory that prevents cron from writing there.

BTW, what are the permissions on /home and /home/micekiller?  They have
to have at least the execute bits set for /home/micekiller/tmp to be
accessible.
HTH,
