The Unix timestamp is in seconds after midnight January 1 1970. A
approximatley calculation can be done with seconds. One minute has 60
seconds and 60 minutes are one hour. One day have 24 hours. But 24 hours
times 7 days are not everytime a week and you should know a year has
sometimes 365 days and sometimes 366 days. All calendar programs which are
spret with GNU/Linux have some knowledge about the deviations.

I think you can use XEmacs on all Windows operating systems. If I have
time, I will install such a great editor on my Windows ME. Windows Notepad
is such a pain.
