Hi everyone!

I think that everyone knows ctime() in glibc:

The ctime(), gmtime() and localtime() functions all take an argument
of data type time_t which represents calendar time. When interpreted
as an absolute time value, it represents the number of seconds
elapsed since 00:00:00 on January 1, 1970, Coordinated Universal Time (UTC).

Now I need to use the function of ctime() in linux kernel, but it
seems that I cannot access ctime() in the linux kernel, right? So I have
to reimplement ctime() in the linux kernel. I found that the algorithm
of glibc ctime() is very complex, I don't understand it. Does anyone has
any good ideas about how to implement ctime()?

Thanks!

Well, everyone here knows about the ctime() function defined by the C
standard.

No idea.

Not here. If you have a working implementation, you might be able to
just copy it into your code, whether you understand the algorithm or
not. If that doesn't work, you'll need to try a Linux-specific
programming group.

We must do something. This is something. Therefore, we must do this.

Thats probably because it needs to be. I'd suggest you study the algo and
understand it...

Ask in comp.unix.progammer. This is not a C question.
