Subject: Use standard interfaces to get timezone offsets.
X-Git-Tag: v1.7~46^2~1
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=559c0f04ba6461997bdfa1cc8eae948dd01693ed;p=users%2Fsagi%2Fnvme-cli.git

Use standard interfaces to get timezone offsets.

Use the tm_gmtoff returned from localtime() rather than the global
timezone.  The formal is more portable, while the latter is specific
to glibc.  There's no good reason to use the glibc specific interface.
