Re: License for \newlib\libc\time\

Hello Heiko,

IANAL, but the first license refers to a URL where to find the referenced BSD license so either that should be considered enough or you should follow that link and add the license found there. I followed it and found a template so I guess you would fill in the template with Red Hat Inc as owner of the Copyright. The code in question is not created/owned by the Regents of California so adding the 2nd license is not correct.

Dear Jeff,

if I understand aright I must copy the first and second licence to my
The first because of "Red Hat Licence" and the second because "Red Hat
Licence" correlates to "BSD".

Is this right?

You only need licences relative to the code you have chosen to

You should keep the source headers in the code and add whatever modification message you want
for any changes you make.

Newlib originated at Cygnus Solutions and was shipped as part of embedded tool sets. The files you mention were originally added/created before my time at Cygnus Solutions and do not have specific licences in them. Normally, files without licences originally added in the early Cygnus days (see the earliest ChangeLog entry) are assumed to be Cygnus and now owned by Red Hat, which is the first licence in COPYING.NEWLIB. In this case we are given the authors. The Arthur David Olson tz code referred to by mktm_r.c is mentioned on the net as public domain. G. Haley (author of mktime.c) is Graham Haley and his contribution to Cygnus is noted in the libc documentation so you will need the Red Hat licence.
