Could somebody with Windows access try example 29?  That example only uses
POSIX compliant time functions like mktime and difftime, but I am not sure
whether the Windows C library provides those or not (or even supplies them
under a different name).

Hi Alan,

I looked into example 21 for Fortran 77 and 95 to incorporate the changes that you recently
made and found to my surprise that they have not been implemented yet. I doubt I will have
time before my holiday (next three weeks) to do the job properly, but I will certainly do
it after that, if no one steps in.
