strftime?

[darren@example.com (Darren Cook)]

I am developing a (Windows console) program that has to be recompiled under
Unix. According to the online-help strftime is not available under Unix, yet
it goes into detail about Posix modifiers. I thought Posix and Unix were
fairly much the same thing - what is the difference?

More importantly, is strftime available under a)Linux, b)Solaris?

BTW, 'man' does not work in my Linux installation. I suspect I told it not
to install a program that man uses. Can someone tell me what that program
is, so I can make sure I include it when I reinstall.

Thanks in advance,

Darren.
