I guess you'd plan to do that like this in the caller:
if (date->local)
tz_name = NULL;
else
tz_name = "";
and then your strftime() doesn't do any %z expansion when tz_name is
NULL.
Yes, or you could look up a time zone name somewhere else -- except we
don't have a way to do that, at least for now.
I was thinking that we would need to have it take the actual time_t, and
then it would be able to do the tzset/localtime dance itself. But since
I don't think we're planning to do that (if anything we'd just handle
the normal localtime() case), the complication it would add to the
interface isn't worth it.
A caller that really needs to do that can, and pass the result as a
string. Not pretty, but at least it's a possibility.
