Re: Using of struct tm in kernel module

The more I work with this operating system, the more I like it.
I understand that development of OS keeps some rules and some philosophy.
And I fully understand that kernel should not care for such thing like 
Monday, Sunday, 29-Feb, 31-Jan, 30-Apr, etc.

Consider please,
Windows is able to work with equivalent of struct tm in kernel and 
contains conversion functions and Linux too.
I accept that this feature is not present in NetBSD (and I am almost 
finished with implementing it just this time).

Not easy to explain details of the overall data flow, important for 
porting to NetBSD is to minimize differences,
Problems to abstract some different os features comes when principles 
are significantly different.
