DEVEL15-cmdebug-human-readable-expiration-time-20071109

add -ctime parameter which produces human readable expiration times.
Doesn't work with OpenAFS for Windows prior to 1.5.28 because time()
was not used in those versions for tracking expiration times.

(cherry picked from commit 578e0d957547e4ac7f39b0559e166fd9eea5f150)
